Description

Technical Field

[0001] This invention relates to a battery pack disconnection device, and more particularly to a battery pack disconnection device for new energy vehicles, belonging to the field of new energy vehicle battery technology. Background Technology

[0002] Currently, with global emphasis on environmental protection and sustainable development, new energy vehicles are becoming increasingly prevalent in the market at an unprecedented pace. Among the various new energy vehicle technologies, lithium battery technology dominates, with most new energy vehicles on the market relying on lithium batteries for power. The widespread use of lithium batteries is due to their significant advantages, with high energy density being particularly prominent. High energy density means that lithium batteries can store a large amount of electrical energy in a relatively small volume and weight, which is crucial for new energy vehicles. It effectively increases the vehicle's range, meeting consumers' needs for long-distance travel, and also helps optimize the overall structural design of the vehicle, making it lighter and more agile.

[0003] Existing battery pack detachment devices for new energy vehicles have several drawbacks in actual use. Since the battery box is installed on the vehicle chassis, the battery pack will fall below the chassis after detachment. This requires workers to pull the battery pack out from under the chassis, which is inconvenient. Furthermore, because the battery box is installed on the vehicle chassis and the vehicle floor is a certain distance from the ground, the battery pack will fall to the ground when it is removed from the battery box. Due to the distance from the ground, the risk of the battery pack exploding upon impact is increased, making it a highly dangerous device. Summary of the Invention

[0004] The main objective of this invention is to address the problems of inconvenient battery pack disassembly and the increased risk of battery pack explosion due to the battery pack's distance from the ground, by providing a battery pack detachment device for new energy vehicles.

[0005] The objective of this invention can be achieved by adopting the following technical solution: A battery pack detachment device for new energy vehicles includes a battery box and a rotating assembly mounted on the battery box. A moving assembly is mounted on the rotating assembly, a supporting assembly is mounted on the moving assembly, a detachment assembly is mounted on the supporting assembly, a connecting assembly is mounted on the detachment assembly, an auxiliary pusher is mounted on the connecting assembly, a main pusher that cooperates with the auxiliary pusher is mounted on the battery box, a lowering assembly is mounted on the connecting assembly, a placement assembly is mounted on the lowering assembly, and a battery pack is mounted on the placement assembly.

[0006] Preferably, the rotating assembly includes a motor, an outer frame, and a support column. The support column is mounted on the battery box, and the outer frame is mounted on one end of the support column. The motor is mounted on the outer frame.

[0007] Preferably, the battery box has multiple sliding rods installed inside, and a slip ring is slidably mounted on each sliding rod. One end of each sliding rod is connected to the battery box via a base block.

[0008] Preferably, the support assembly includes a lifting rod and a connecting rod, with the lifting rod mounted on the slip ring and the connecting rod mounted on the lifting rod.

[0009] Preferably, the moving component includes a gear, a rack, and a push rod. The push rod is mounted on the lifting rod, and a rack is mounted on one end of the push rod. The output end of the motor is equipped with a gear that meshes with the rack.

[0010] Preferably, the detachment assembly includes a movable rod, a movable ring, a second spring, a connecting ring, and a base column. The movable rod is mounted on the lifting rod, the movable ring is slidably mounted on the movable rod, the connecting ring is mounted on the movable rod, the movable ring is connected to the connecting ring through the second spring, and the base column is mounted on the movable ring.

[0011] Preferably, the connecting assembly includes a support plate and a base frame. The support plate is installed at one end of the base column, and the base frame is installed on the support plate. The bottom of the base frame is connected to the auxiliary push block, and one end of the auxiliary push block is provided with a pressing slope.

[0012] Preferably, a cover is installed at one end of the lifting rod.

[0013] Preferably, the lowering assembly includes a guide rod, a guide ring, a connecting block, a bottom rod, a connecting plate, and a first spring. The guide rod is mounted on the support plate, the guide ring is slidably mounted on the guide rod, the connecting block is mounted on the guide ring, the bottom rod is mounted on the connecting block, and the connecting plate is mounted on the guide rod. The guide ring is connected to the connecting plate via the first spring.

[0014] Preferably, a placement frame is installed at one end of the base rod, a compression block is installed on the placement frame, and a battery pack is provided on the placement frame.

[0015] Beneficial technical effects of the present invention: 1. The new energy vehicle battery pack detachment device according to the present invention includes a motor. When the motor starts, it drives the gear to rotate. When the gear rotates, it drives the rack to move. When the rack moves, it drives the lifting rod to move. When the lifting rod moves, it drives the cover to move, thereby opening the battery box. When the lifting rod moves, it drives the placement frame to move, removing the battery pack from the battery box. At this time, the auxiliary push block moves out of the battery box, the second spring returns to its original position, and it drives the moving ring to move. When the moving ring moves, it drives the support plate to move, moving the placement frame away from the battery pack, which facilitates the detachment of the battery pack. It can also push the battery pack away from the underside of the car chassis and move it to the side of the car, which is convenient for battery pack maintenance operations.

[0016] 2. By setting up a motor, the motor starts and drives the gear to rotate. When the gear rotates, it drives the rack to move, moving the lifting rod and the placement frame out of the battery box. When the squeezing block is removed from the battery box, the first spring returns to its original position, causing the guide ring to slide on the guide rod, which in turn moves the placement frame and brings the battery pack closer to the ground. When the battery pack is close to the ground, the lifting rod continues to move, causing the auxiliary pushing block to move. When the inclined end of the auxiliary pushing block is removed from the battery box, the second spring returns to its original position, causing the placement frame to move. This allows the battery pack to detach from the placement frame and fall to the ground. Because the battery pack is close to the ground, the risk of explosion when the battery pack falls is reduced.

[0020] like Figures 1-11As shown, the new energy vehicle battery pack detachment device provided in this embodiment includes a battery box 1 and a rotating assembly mounted on the battery box 1. A moving assembly is mounted on the rotating assembly, a supporting assembly is mounted on the moving assembly, a detachment assembly is mounted on the supporting assembly, a connecting assembly is mounted on the detachment assembly, an auxiliary pusher block 93 is mounted on the connecting assembly, a main pusher block 9 that cooperates with the auxiliary pusher block 93 is mounted on the battery box 1, a lowering assembly is mounted on the connecting assembly, a placing assembly is mounted on the lowering assembly, and a battery pack 12 is mounted on the placing assembly. The rotating assembly includes a motor 2, an outer frame 21, and a support column 22. The support column 22 is mounted on the battery box 1, and the outer frame 21 is mounted at one end of the support column 22. The motor 2 is mounted on the outer frame 21. Multiple [unclear text - possibly related to battery pack detachment devices] are installed inside the battery box 1. A sliding rod 6 has a sliding ring 61 slidably mounted on it. One end of the sliding rod 6 is connected to the battery box 1 via a base block 62. The support assembly includes a lifting rod 5 and a connecting rod 51. The lifting rod 5 is mounted on the sliding ring 61, and the connecting rod 51 is mounted on the lifting rod 5. The moving assembly includes a gear 8, a rack 81, and a push rod 82. The push rod 82 is mounted on the lifting rod 5, and a rack 81 is mounted on one end of the push rod 82. The output end of the motor 2 is equipped with a gear 8 that meshes with the rack 81. The disengagement assembly includes a moving rod 7, a moving ring 71, a second spring 72, a connecting ring 73, and a base column 74. The moving rod 7 is mounted on the lifting rod 5, and the moving ring 71 is slidably mounted on the moving rod 7. The connecting ring 73 is mounted on the moving rod 7, and the moving ring 71 is connected to the connecting ring via the second spring 72. 73. A base post 74 is installed on the moving ring 71. A cover 11 is installed at one end of the lifting rod 5. A motor 2 is installed. When the motor 2 starts, it drives the gear 8 to rotate. When the gear 8 rotates, it drives the rack 81 to move. When the rack 81 moves, it drives the lifting rod 5 to move. When the lifting rod 5 moves, it drives the cover 11 to move, thereby opening the battery box 1. When the lifting rod 5 moves, it drives the placement rack 3 to move, removing the battery pack 12 from the battery box 1. At this time, the auxiliary push block 93 moves out of the battery box 1, the second spring 72 returns to its original position, and drives the moving ring 71 to move. When the moving ring 71 moves, it drives the support plate 91 to move, moving the placement rack 3 away from the battery pack 12, making it easier for the battery pack 12 to detach and push the battery pack 12 away from the underside of the car chassis to the side of the car. To facilitate maintenance of the battery pack 12, the outer frame 21 and support column 22 work together to support the motor 2. The sliding rod 6 and sliding ring 61 are slidably connected to guide and limit the lifting rod 5. The base block 62 supports the sliding rod 6. The lifting rod 5 and connecting rod 51 work together to support the moving rod 7. The moving ring 71 is slidably connected to the moving rod 7 to guide and limit the support plate 91. The top rod 82 supports the rack 81. The main push block 9, auxiliary push block 93, and second spring 72 work together to reset the placement frame 3. The auxiliary push block 93 moves, and when the pressing slope of the auxiliary push block 93 contacts the main push block 9...The auxiliary push block 93 continues to move, causing the second spring 72 to extend, which in turn causes the moving ring 71 to slide on the moving rod 7. When the moving ring 71 slides, it causes the support plate 91 to move, and when the support plate 91 moves, it causes the placement frame 3 to move and reset.

[0021] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the connecting assembly includes a support plate 91 and a base frame 92. The support plate 91 is mounted on one end of the base column 74, and the base frame 92 is mounted on the support plate 91. The bottom of the base frame 92 is connected to an auxiliary push block 93. One end of the auxiliary push block 93 is provided with a pressing slope. The lowering assembly includes a guide rod 4, a guide ring 41, a connecting block 42, a base rod 43, a connecting plate 45, and a first spring 46. The guide rod 4 is mounted on the support plate 91, the guide ring 41 is slidably mounted on the guide rod 4, the connecting block 42 is mounted on the guide ring 41, and the base rod 46 is mounted on the connecting block 42. 3. A connecting plate 45 is installed on the guide rod 4. The guide ring 41 is connected to the connecting plate 45 through a first spring 46. A placement frame 3 is installed at one end of the bottom rod 43. A pressing block 31 is installed on the placement frame 3. A battery pack 12 is placed on the placement frame 3. A motor 2 is installed. When the motor 2 starts, it drives the gear 8 to rotate. When the gear 8 rotates, it can drive the rack 81 to move, moving the lifting rod 5 and the placement frame 3 out of the battery box 1. When the pressing block 31 is moved out of the battery box 1, the first spring 46 returns to its original position, causing the guide ring 41 to slide on the guide rod 4. The movable placement frame 3 moves, bringing the battery pack 12 closer to the ground. Once the battery pack 12 is close to the ground, the lifting rod 5 continues to move, moving the auxiliary push block 93. When the inclined end of the auxiliary push block 93 is removed from the battery box 1, the second spring 72 resets, moving the placement frame 3 to detach the battery pack 12 from the placement frame 3. The detached battery pack 12 falls to the ground. Because the battery pack 12 is close to the ground, the risk of explosion upon falling is reduced. The support plate 91 and the base frame 92 work together to facilitate the movement of the auxiliary push block 93. The support is provided by a base rod 43 to support the placement rack 3, and a guide ring 41 that is slidably connected to a guide rod 4 to guide and limit the placement rack 3. The compression block 31 and the first spring 46 cooperate to move the placement rack 3 into the battery box 1 for storage. When the compression block 31 contacts the battery box 1, the compression block 31 moves continuously, causing the first spring 46 to shorten, which can drive the placement rack 3 to rise. When the bottom of the placement rack 3 is flush with the inner wall of the battery box 1, the placement rack 3 continues to move into the battery box 1 for storage.

[0022] In this embodiment, as Figures 1-11 As shown in the figure, the working process of a new energy vehicle battery pack disconnection device provided in this embodiment is as follows: Step 1: The motor 2 starts and drives the gear 8 to rotate. When the gear 8 rotates, it can drive the rack 81 to move. When the rack 81 moves, it drives the lifting rod 5 to move. When the lifting rod 5 moves, it drives the cover 11 to move, thereby opening the battery box 1. When the lifting rod 5 moves, it drives the placement rack 3 to move, moving the battery pack 12 out of the battery box 1. When the squeezing block 31 is removed from the battery box 1, the first spring 46 returns to its original position, causing the guide ring 41 to slide on the guide rod 4, driving the placement rack 3 to move, and moving the battery pack 12 closer to the ground. Step 2: When the battery pack 12 is close to the ground, the lifting rod 5 continues to move, which drives the auxiliary push block 93 to move. The second spring 72 returns to its original position, which drives the moving ring 71 to move. When the moving ring 71 moves, it drives the support plate 91 to move, which drives the placement rack 3 away from the battery pack 12. At this time, the battery pack 12 is detached from the placement rack 3, and the staff performs maintenance on the battery pack 12.

[0023] In summary, in this embodiment, the new energy vehicle battery pack detachment device, by setting up a motor 2, drives the gear 8 to rotate when the motor 2 starts. When the gear 8 rotates, it drives the rack 81 to move. When the rack 81 moves, it drives the lifting rod 5 to move. When the lifting rod 5 moves, it drives the cover 11 to move, thereby opening the battery box 1. When the lifting rod 5 moves, it drives the placement frame 3 to move, removing the battery pack 12 from the battery box 1. At this time, the auxiliary push block 93 moves out of the battery box 1, the second spring 72 resets, and drives the moving ring 71 to move. When the moving ring 71 moves, it drives the support plate 91 to move, moving the placement frame 3 away from the battery pack 12, facilitating the removal of the battery pack 12. The battery pack 12 can be detached and pushed away from the underside of the vehicle chassis to the side of the vehicle, facilitating maintenance by staff. The outer frame 21 and support column 22 cooperate to support the motor 2. The sliding rod 6 and sliding ring 61 are slidably connected to guide and limit the lifting rod 5. The base block 62 supports the sliding rod 6. The lifting rod 5 and connecting rod 51 cooperate to support the moving rod 7. The moving ring 71 is slidably connected to the moving rod 7 to guide and limit the support plate 91. The top rod 82 facilitates gear adjustment. The rack 81 provides support, and the main push block 9, auxiliary push block 93, and second spring 72 work together to facilitate the resetting of the placement rack 3. A motor 2 is installed; when it starts, it drives the gear 8 to rotate. The rotation of the gear 8 moves the rack 81, removing the lifting rod 5 and the placement rack 3 from the battery box 1. When the pressing block 31 is removed from the battery box 1, the first spring 46 resets, causing the guide ring 41 to slide on the guide rod 4, moving the placement rack 3 and bringing the battery pack 12 closer to the ground. Once the battery pack 12 is close to the ground, the lifting rod 5 continues to move, moving the auxiliary push block 93 and pushing the inclined end of the auxiliary push block 93 from the battery box 1. When the battery pack 12 is removed, the second spring 72 returns to its original position, causing the placement rack 3 to move and detach the battery pack 12 from the placement rack 3. After detachment, the battery pack 12 falls to the ground. Since the battery pack 12 is close to the ground, the risk of explosion when the battery pack falls is reduced. The support plate 91 and the base frame 92 cooperate to support the auxiliary push block 93. The base rod 43 supports the placement rack 3. The guide ring 41 is slidably connected to the guide rod 4 to guide and limit the placement rack 3. The compression block 31 cooperates with the first spring 46 to move the placement rack 3 into the battery box 1 for storage.
