Description

Technical Field

[0001] This invention relates to the field of battery swapping station technology, and in particular to a device for removing impurities from battery packs used in battery swapping stations. Background Technology

[0002] In recent years, with the development of new energy vehicle technology and the country's strong support for battery swapping, electric vehicles are becoming increasingly common. To alleviate range anxiety, vehicles can be quickly recharged at battery swapping stations by replacing the battery pack in just a few minutes or even a minute, which is significantly more advantageous than charging.

[0003] When electric vehicles are in rainy or snowy weather or on bad road conditions, ice, mud and other debris may appear at the bottom of the battery pack, and the battery pack locking mechanism may be covered by debris. These situations may prevent the battery pack from being replaced smoothly. At the same time, battery packs carrying ice and debris may contaminate the equipment compartment of the battery swapping station, and water, mud and other debris may even pose a safety hazard to the battery swapping station. Summary of the Invention

[0055] See Figure 1 As shown, this invention provides a debris removal device for battery packs in a battery swapping station, comprising: a support frame 9, a moving platform, and a debris removal device; the moving platform includes a moving mechanism 3 and a supporting platform 2, the moving mechanism 3 driving the supporting platform 2 to move is mounted on the support frame 9, and the moving mechanism 3 is driven and connected to the supporting platform 2; the debris removal device, which moves synchronously with the supporting platform 2, includes a driving mechanism 8 and a debris removal mechanism, the driving mechanism 8 being mounted on the supporting platform 2, the debris removal mechanism being mounted on the supporting platform 2, and the driving mechanism 8 driving and connecting to the debris removal mechanism, for removing debris from the bottom of the battery pack. It should be noted that...

[0056] When replacing battery packs at battery swapping stations for new energy vehicles, debris may adhere to the bottom of the battery pack and the battery pack locking device, affecting the replacement process. The moving mechanism 3 of this invention moves the carrying platform 2, enabling the debris removal mechanism to reach the area where the debris is located at the bottom of the battery pack and the area where the battery pack locking device is located. The debris is removed by the debris removal mechanism, ensuring that the bottom of the battery pack and the battery pack locking device are clean, preventing debris from affecting the battery pack replacement process, and ensuring the safety of the battery swapping station.

[0057] See Figure 1 and Figure 2As shown in the specific example of this application, the impurity removal mechanism includes at least one impurity removal roller assembly. The impurity removal roller assembly includes a first rotating roller 11, a second rotating roller 12, and a third rotating roller 13 arranged side by side in sequence. Cleaners 6 are provided on the outer circumferential surfaces of the first rotating roller and the second rotating roller 12. The rotation directions of the first rotating roller 11 and the second rotating roller 12 are opposite. A sweeper 7 is provided on the outer circumferential surface of the second rotating roller 12. In actual use, the moving mechanism 3 drives the carrying platform 2 to move forward or backward below the area where the impurities are located. The cleaners 6 on the first rotating roller 11 and the third rotating roller 13 break up the impurities at the bottom of the battery pack. The sweeper 7 on the second rotating roller 12 cleans the dust at the bottom of the battery pack and the residual debris after cleaning by the cleaners 6, ensuring the cleanliness of the bottom of the battery pack and preventing impurities from affecting the battery pack replacement process, thus ensuring the safety of the battery swapping station. In this embodiment, the hard protrusion on the first rotating roller has an arc-shaped end away from the first rotating roller 11, and the hard protrusion on the third rotating roller 13 has an arc-shaped end away from the third rotating roller 13. This further prevents the hard protrusion from damaging the bottom of the battery pack during the high-speed rotation of the first rotating roller 11 and the second rotating roller 12. However, this application does not limit the specific structure of the end of the hard protrusion, which will be described here. It should also be noted that this application does not limit the specific mechanism of the cleaner 6 and the sweeper 7. Any specific structure that can clean the bottom of the battery pack and the locking device is within the protection scope of this application.

[0058] See Figure 1 and Figure 2 As shown in the specific example of this application, the cleaner 6 includes a plurality of hard protrusions evenly distributed on the outer peripheral surfaces of the first rotating roller 11 and the third rotating roller 13; the sweeper 7 includes a brush disposed on the outer peripheral surface of the second rotating roller 12. It is worth mentioning that, in this embodiment, the rotation centers of the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13 are located on the same horizontal plane. The diameter of the outer surface of the second rotating roller 12 plus the brush is larger than the diameter of the outer surface of the first rotating roller plus the hard protrusions, and larger than the diameter of the outer surface of the third rotating roller 13 plus the hard protrusions. This can prevent the hard protrusions from making hard contact with the lower surface of the battery pack during the rotation and impurity removal process of the first rotating roller 11 and the third rotating roller 13, thus avoiding damage to the bottom of the battery pack caused by the hard protrusions contacting the lower surface of the battery pack.

[0059] See Figure 1 and Figure 6As shown in a specific example of this application, the drive mechanism 8 includes a power motor 81, a first rotating wheel 83, a first rotating gear 86, and a second rotating wheel 88. The motor is mounted on the support platform 2, and the output shaft of the motor is driven to connect to the first rotating wheel 83 via a first transmission belt 82. The first rotating wheel 83 is fixedly connected to the first rotating roller 11 and drives the first rotating roller 11 to rotate synchronously. The first rotating wheel 83 is driven to connect to the synchronous gear 85 via a second transmission belt 84. The first rotating gear 86 meshes with the synchronous gear and is fixedly connected to the second rotating roller 12, driving the second rotating roller 12 to rotate synchronously. The first rotating gear 86 is driven to connect to the second rotating wheel 88 via a third transmission belt 87. The second rotating wheel 88 is fixedly connected to the third rotating roller 13 and drives the third rotating roller 13 to rotate synchronously. Specifically, to ensure that the power motor 81 remains energized during the movement of the support platform 2, the power motor 81 is connected to an external power source along with the second wiring harness 89. It should be noted that, in this embodiment, the bearing platform 2 includes a bearing plate 21 and two support plates 22 arranged parallel to the bearing plate 21. The two ends of the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13 are respectively rotatably mounted on a support plate 22. The power motor 81 is mounted on the bearing plate 21, and the output shaft of the power motor 81 passes through any support plate 22. The first rotating wheel 83 has a first rotating platform 831 that cooperates with the first transmission belt 82 and a second rotating platform 832 that cooperates with the second transmission belt 84. The synchronous gear 85 has a first boss 851 for cooperating with the second transmission belt 84, and the first rotating gear 86 has a second boss 861 for cooperating with the third transmission belt 87.

[0060] In actual use, the power motor 81 starts, and the output shaft of the power motor 81 drives the first rotating wheel 83 to rotate via the first transmission belt 82, which in turn drives the first rotating roller 11 to rotate synchronously. The first rotating wheel 83 drives the synchronous gear 85 to rotate via the second transmission belt 84. The first rotating gear 86 externally meshes with the synchronous gear 85, so that the first rotating gear 86 and the synchronous gear 85 rotate in opposite directions. At the same time, the first rotating gear 86 drives the second rotating roller 12 to rotate. The first rotating gear 86 drives the second rotating wheel 88 to rotate via the third transmission belt 87, and the second rotating wheel 88 drives the third rotating roller 13 to rotate. In this example, the drive mechanism 8 keeps the first rotating roller 11 and the third rotating roller 13 rotating in opposite directions. Specifically, both the first rotating roller 11 and the third rotating roller 13 rotate towards the second rotating roller 12, which facilitates the collection of debris broken during the cleaning of debris at the bottom of the battery pack, avoiding the danger of debris splashing. It should be noted that the drive mechanism 8 of this application also includes a protective cover, which is installed on the support plate 22 and encloses the first rotating wheel 83, the synchronous gear 85, the first rotating gear 86 and the second rotating wheel 88 to prevent dust and debris from falling in, and to ensure the stable operation of the first rotating wheel 83, the synchronous gear 85, the first rotating gear 86 and the second rotating wheel 88. This improves the long-term stable operation of the impurity removal equipment of this application. Although no specific illustration is given in the accompanying drawings, those skilled in the art can understand the installation of the protective cover after knowing the technical solution of this application. It should be noted that in other embodiments, the drive mechanism 8 includes a first motor 311, a first driving gear, a first synchronous gear, a second synchronous gear, a first driven gear, and a second driven gear. The first motor 311 is mounted on the support plate 21. The output shaft of the first motor 311 is connected to the first driving wheel via a first belt, driving the first driving wheel to rotate. The first driving wheel is fixedly connected to the second rotating roller 12. The first driven gear and the second driven gear are respectively externally meshed with the two sides of the first driving gear. Both the first driven gear and the second driven gear are rotatably mounted on the support plate 22. The first driven gear is connected to the first synchronous gear via a second belt. The first synchronous gear is fixedly connected to the first rotating roller. The second driven gear is connected to the second synchronous gear via a third belt. The second synchronous gear is fixedly connected to the third rotating roller 13. The first rotating roller and the second rotating roller 12 are in opposite rotation directions. Therefore, this application does not impose specific limitations on the specific structure of the drive mechanism 8. Any specific structure of the drive mechanism 8 that enables the first rotating roller 11 and the third rotating roller to be in different rotation directions is within the protection scope of this application.

[0061] See Figures 1 to 3As shown in the specific example of this application, the moving mechanism 3 includes a first moving mechanism 3, a second moving mechanism 3, and a moving frame; the first moving mechanism 3 is mounted on the support 9 and drives the moving frame to move forward or backward along a first direction; the second moving mechanism 3 is mounted on the moving frame and drives the carrying platform 2 to move forward or backward along a second direction; the first direction and the second direction are two mutually perpendicular directions in the same plane. Specifically, in this embodiment, the support 9 includes a rectangular frame composed of four surrounding plates 91, and the first moving mechanism 3 is located within the frame, and the second moving mechanism 3 is located within the frame.

[0062] See Figures 1 to 3 As shown in the specific example of this application, the first moving mechanism 3 includes a first motor 311, a first transmission mechanism, and a first slider; the first motor 311 is mounted on a bracket 9; the first transmission mechanism includes a first bevel gear 312, a second bevel gear 313, a first lead screw 314, and a first guide rod 315. The first lead screw 314 is rotatably mounted on the bracket 9, the first bevel gear 312 is sleeved on the output shaft of the first motor 311, the second bevel gear 313 is sleeved on the end of the first lead screw 314, and the first bevel gear 312 and the second bevel gear 313 are meshed together; the first guide rod 315 is mounted on the bracket 9 and is arranged parallel to the first lead screw 314, and a first synchronizing block is slidably sleeved on the first guide rod 315; the first slider is sleeved on the first lead screw 314; the moving frame is fixedly connected to the first slider and the first synchronizing block. Specifically, the first motor 311 is mounted on the enclosure 91, and there is one first guide rod 315, which is set parallel to the first lead screw 314, with each end of the first guide rod 315 fixedly connected to an enclosure 91. In actual use, when the first motor 311 is started, its rotation drives the first bevel gear 312 sleeved on the output shaft of the first motor 311. The first bevel gear 312 drives the meshing second bevel gear 313 to rotate, and the second bevel gear 313 drives the first lead screw 314 to rotate, causing the first slider to move on the first lead screw 314. The first slider drives the moving frame to move, and the first synchronizing block cooperates with the first slider to ensure that the moving frame maintains stable movement. In this embodiment, the forward or reverse rotation of the first motor 311 is used to control the moving frame to move forward or backward in the first direction.

[0063] See Figures 1 to 3As shown in the illustration, in one specific example of this application, the movable frame includes a movable frame 34, and a first connecting plate 35 and a second connecting plate disposed on the movable frame 34. The first connecting plate 35 is fixedly connected to a first slider, and the second connecting plate is fixedly connected to a first synchronization block. This embodiment provides a specific structure for the movable frame, where the first connecting plate 35 cooperates with the first slider, and the second connecting plate cooperates with the first synchronization block, ensuring that the movable frame can move while reducing its weight. In other embodiments, the movable frame has a base plate at the bottom for fixing the first slider and the first synchronization block together. Therefore, this application does not limit the specific structure of the movable frame, and can ensure that the structure of the movable frame connecting the first slider and the first synchronization block is within the protection scope of this application.

[0064] See Figures 1 to 3 As shown in the specific example of this application, the second moving mechanism 3 includes a second motor 321, a second transmission mechanism, and a second slider; the second motor 321 is mounted on the moving frame 34; the second transmission mechanism includes a third bevel gear 322, a fourth bevel gear 323, a second lead screw 324, and a second guide rod 325. The second lead screw 324 is rotatably mounted on the moving frame 34, the third bevel gear 322 is sleeved on the output shaft of the second motor 321, the fourth bevel gear 323 is sleeved on the end of the second lead screw 324, and the third bevel gear 322 and the fourth bevel gear 323 mesh; the second guide rod 325 is mounted on the moving frame 34 and is arranged parallel to the second lead screw 324, and a second synchronizing block is slidably sleeved on the second guide rod 325; the second slider is sleeved on the second lead screw 324; the bearing platform 2 is fixedly connected to the second slider and the second synchronizing block. Specifically, to ensure that the second motor 321 remains energized while moving with the moving frame 34, the second motor 321 is connected to an external power source via the first wiring harness 326. In actual use, when the second motor 321 is started, its rotation drives the third bevel gear 322 to rotate, which in turn drives the fourth bevel gear 323 to rotate. The fourth bevel gear 323 then drives the second lead screw 324 to rotate, causing the second slider to move on the second lead screw 324. The support plate 21 moves along with the second slider, and the second synchronizing block on the support plate 21 moves on the second guide rod 325, ensuring smooth movement of the support plate 21. In this embodiment, the forward or reverse rotation of the second motor 321 controls the forward or backward movement of the support plate 21 in the second direction. The forward or reverse rotation of the first motor 311 controls the moving frame to move forward or backward in the first direction. The cooperation between the first motor 311 and the second motor 321 enables the support plate 21 to move to the location at the bottom of the car where debris needs to be cleaned, ensuring accurate cleaning of the debris.

[0065] The specific structure of the above-mentioned moving mechanism is a specific example of this application. In other embodiments, the moving mechanism is implemented by cylinder pushing in order to ensure the free movement of the bearing platform 2 in the first direction and the second direction. Two sets of cylinders are perpendicular to each other and are used to push the bearing platform 2 to move in the first direction and the second direction. Therefore, this application does not limit the specific structure of the moving mechanism. Any specific structure that can enable the bearing platform 2 to move in the mutually perpendicular first direction and the second direction is within the protection scope of this application.

[0066] See Figure 1 and Figure 4 As shown, the impurity removal equipment of this application also includes an air jet device 4, which includes a controller, a drive motor 41, an air compressor 42, a main pipe 44, and multiple branch pipes 45. The drive motor 41, which drives the air compressor 42, is mounted on a bracket 9. The air compressor 42 is mounted on the bracket 9, and the main pipe 44 surrounds the bracket 9. One end of the main pipe 44 is connected to the air outlet of the air compressor 42, and the other end is a closed structure. Multiple branch pipes 45 are distributed on the main pipe 44, and the bottom of each branch pipe 45 is connected to the main pipe 44. Each branch pipe 45 has an electric valve between it and the main pipe 44, and the top of each branch pipe 45 is an air jet port. The controller is mounted on the bracket 9 and is electrically connected to each electric valve to control the air jetting or closing of each branch pipe 45. Specifically, in this embodiment, the main pipe 44 is distributed around the outer periphery of the frame, and multiple connecting rods 46 are evenly distributed around the outer periphery of the frame. The outer end of each connecting rod 46 is fixedly connected to the main pipe 44, and branch pipes 45 are distributed on the main pipe 44. In one embodiment, the top of the branch pipe 45 has a certain inclination angle to blow dust from the bottom of the car onto the receiving hopper 53, facilitating material discharge. In actual use, the first motor 311 and the second motor 321 work together to move the bearing plate 21 to the location of the debris. The controller activates the electric valve on the nearby branch pipe 45, causing high-pressure gas to be ejected from the outlet of the branch pipe 45 to blow away the small debris adsorbed on the bottom of the battery pack and the battery pack locking device.

[0067] In cold weather, ice buildup under the car increases wear on the hard protrusions on the first rotating roller 11 and the third rotating roller 13. (See also...) Figure 1 and Figure 4As shown, the jetting device 4 in this application also includes a heater 43, which is disposed between the air compressor 42 and the main pipe 44. In actual use, the heating device draws air into the main pipe 44, causing the jet nozzle of the branch pipe 45 to spray hot air to melt and blow off the ice on the bottom of the car. Combined with the hard protrusions on the first rotating roller 11 and the third rotating roller 13, and the brush on the second rotating roller 12, the combination of multiple cleaning methods improves the cleaning effect on the bottom of the battery pack and the battery pack locking device, speeds up the removal of impurities from the bottom of the car, reduces the wear of the hard protrusions on the first rotating roller 11 and the third rotating roller 13, and increases the service life of the impurity removal device.

[0068] See Figure 1 and Figure 5 As shown, the impurity removal device of this application also includes a collection device 5, which includes a receiving hopper 53, a connecting hose 52, and a vacuum cleaner 51. The receiving hopper 53 is installed on the support platform 2, and the top opening 211 of the receiving hopper 53 is located below the impurity removal mechanism. One end of the connecting hose 52 is connected to the bottom of the receiving hopper 53, and the other end is connected to the feed inlet of the vacuum cleaner 51. Specifically, in this embodiment, the bottom of the receiving hopper 53 is installed on the support plate 21, and the support plate 21 has an opening for the connecting hose 52 to pass through. The receiving hopper 53 has a conical structure, and the upper opening 211 of the conical hopper is located below the first rotating roller 11, the second rotating roller 12, and the third rotating roller 13. The bottom of the receiving hopper 53 has a discharge port 531 connected to the connecting hose 52, which facilitates the sliding of debris and fragments in the hopper. During the cleaning of the bottom of the battery pack and the battery pack locking device, the vacuum cleaner 51 is turned on. The suction power of the vacuum cleaner 51 draws debris and dust into the receiving hopper 53, and then into the vacuum cleaner 51 through the connecting hose 52, ensuring the cleanliness of the battery swapping station. It should be noted that this application does not limit the installation location of the dust collector; it can be installed in a suitable location according to actual needs.
