Description

Technical Field

[0001] This utility model relates to the field of automotive battery replacement technology, specifically to an auxiliary device for automotive battery replacement. Background Technology

[0002] Most new energy vehicles are electric-driven and require a large number of battery boxes for vehicle use. The battery boxes are usually installed on the chassis of the vehicle via battery brackets. When replacing, inspecting and repairing the vehicle battery, the vehicle needs to be lifted up and the battery brackets need to be removed from the bottom to take out the battery.

[0003] A battery replacement auxiliary trolley, as described in an existing Chinese patent (authorization announcement number: CN217146033U), includes a trolley body and a push-pull structure. The trolley body includes a base plate, a baffle, and multiple wheels. The base plate is horizontally positioned, and the baffle surrounds its outer perimeter, forming a support space for placing batteries. The top of the support space has an opening. The multiple wheels are spaced apart on the baffle along a first direction and located on both sides of the base plate along a second direction, perpendicular to each other. The push-pull structure includes a support frame and a handrail. The bottom of the support frame is connected to one end of the base plate, and the top of the support frame is connected to the handrail. The end of the baffle away from the support frame has an opening for the battery to pass through, communicating with the support space. The end of the base plate away from the support frame has a guide ramp sloping downwards from its edge. The support space carries the battery, the baffle prevents the battery from falling, and the wheels, in conjunction with the trolley body, transport the battery to the battery charging area, reducing the workload of the operators.

[0004] The aforementioned documents, by setting up a mobile vehicle, can assist operators in more easily transporting batteries, thereby reducing workload. However, when using the vehicle in the aforementioned documents to replace batteries, the staff still need to first remove the heavy battery pack from the bottom of the car and then manually carry it onto the vehicle. Since car battery packs are usually heavy and located low, this process is not only cumbersome but also consumes a lot of physical strength, so the workload of the staff has not been fundamentally improved and the operation is extremely inconvenient. Therefore, this application provides an auxiliary device for replacing car batteries. Utility Model Content

[0024] The following is in conjunction with the appendix Figure 1—5. The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] This application discloses an auxiliary device for replacing automobile batteries.

[0026] Reference Figure 1 A car battery replacement auxiliary device includes a car body 1, a handle 2 symmetrically fixedly connected to one side of the car body 1, a controller 3 fixedly connected to the top of the car body 1, a support frame 4 fixedly connected to the top of the car body 1, an adjusting block 5 slidably connected inside the support frame 4, a connecting plate 6 fixedly connected to one side of the adjusting block 5, a support plate 7 slidably connected to the top of the connecting plate 6, and lighting lamps 8 symmetrically fixedly connected to both sides of the support plate 7. The lighting lamps 8 are electrically connected to the controller 3. A lifting component is installed inside the support frame 4, a clamping component is installed inside the support plate 7, and auxiliary components are installed on both sides of the car body 1.

[0027] In use, first pull the device to one side of the bottom of the car, then start the lifting assembly via controller 3. The lifting assembly allows for precise adjustment of the position of the adjusting block 5, which in turn causes the connecting plate 6 and the support plate 7 to gradually rise until the top surface of the support plate 7 is tightly fitted to the bottom of the car battery pack. At this point, the clamping assembly inside the support plate 7 can be activated to clamp and fix the sides of the battery pack. Then, the battery pack can be manually removed and separated from the car. Next, reverse the operation of the lifting assembly to lower the connecting plate 6 and the support plate 7. With the assistance of the clamping assembly, the battery pack can be firmly held on the support plate 7, preventing it from shaking and falling off when moving. Finally, the auxiliary assembly can easily push the car body 1 to transport the battery pack. Therefore, during the battery pack replacement process, it can effectively reduce the workload of the staff, assist in battery pack replacement, eliminate the need for manual handling of the battery pack, reduce physical exertion, and effectively improve work efficiency.

[0028] Reference Figure 1 and Figure 2 The support frame 4 has grooves 9 on both sides inside. A motor 10 is fixedly connected to the bottom of one of the grooves 9. A threaded rod 11 is fixedly connected to the output end of the motor 10. Both ends of the adjusting block 5 are slidably connected in the groove 9. One end of the adjusting block 5 is threadedly connected to the threaded rod 11. The motor 10 is electrically connected to the controller 3. A guide rod 12 is fixedly connected inside the other groove 9. The end of the adjusting block 5 away from the threaded rod 11 is slidably connected to the guide rod 12.

[0029] When the height of the adjusting block 5 needs to be adjusted, the motor 10 can be started by the controller 3 to drive the threaded rod 11 to rotate. Since one end of the adjusting block 5 is threadedly connected to the threaded rod 11, the rotation of the threaded rod 11 will drive the adjusting block 5 to slide along the inner wall of the groove 9. At the same time, the end of the adjusting block 5 away from the threaded rod 11 slides on the guide rod 12 to limit the adjustment block 5 and prevent the adjusting block 5 from rotating. At this time, by adjusting the position of the adjusting block 5, the connecting plate 6 and the support plate 7 can be moved up and down until the top surface of the support plate 7 is tightly attached to the bottom surface of the car battery pack.

[0030] Reference Figure 1 and Figure 3 A cylinder 13 is fixedly connected to one side of the adjusting block 5. A sliding groove 14 is symmetrically opened on the top of the connecting plate 6. A slider 15 is symmetrically fixedly connected to the bottom of the support plate 7. The slider 15 is slidably connected in the sliding groove 14. The output end of the cylinder 13 is fixedly connected to one end of the support plate 7. The cylinder 13 is electrically connected to the controller 3.

[0031] When the support plate 7 cannot reach the bottom of the battery pack, the controller 3 can start the cylinder 13. Since the output end of the cylinder 13 is fixedly connected to one end of the support plate 7, when the cylinder 13 extends, it will push the support plate 7 and drive the slider 15 to slide inside the slide groove 14, thereby pushing the support plate 7 forward until the support plate 7 is moved to the bottom of the battery pack. This greatly improves the practicality and convenience of the device and better adapts to different vehicle conditions.

[0032] Reference Figure 1 and Figure 4 The clamping assembly includes a second motor 16 fixedly connected to the top surface inside the support plate 7. A gear 17 is fixedly connected to the output end of the second motor 16. Guide blocks 18 are symmetrically fixedly connected inside the support plate 7. A rack 19 is slidably connected inside each of the two guide blocks 18. A connecting block 20 is fixedly connected to one end of each of the two racks 19. A sliding plate 21 is symmetrically fixedly connected to the top of each of the two connecting blocks 20. A clamping plate 22 is fixedly connected to the top of each of the two sliding plates 21. Two guide grooves 23 are symmetrically opened on the top of the support plate 7. The two sliding plates 21 are slidably connected in the corresponding guide grooves 23. The second motor 16 is electrically connected to the controller 3. A rubber anti-slip pad 24 is fixedly connected to one side of the clamping plate 22 and the top of the support plate 7.

[0033] Once the top of the support plate 7 is in contact with the bottom of the battery pack, the controller 3 can start the motor 16 to drive the gear 17 to rotate. Since both racks 19 are meshed with the gear 17, the rotation of the gear 17 will cause the two racks 19 to slide in opposite directions along the inner wall of the guide block 18. At this time, the racks 19 will drive the two connecting blocks 20 to move, causing the two connecting blocks 20 to drive the two sliding plates 21 to slide along the inner wall of the guide groove 23. At the same time, the two sliding plates 21 will drive the two clamping plates 22 to move closer to each other until the two clamping plates 22 are tightly in contact with both sides of the battery pack. At this time, the two rubber anti-slip pads 24 can increase the friction between the clamping plates 22 and the support plate 7 and the battery pack, improve the clamping stability, and prevent the battery pack from falling off, so that the battery pack can stay firmly on the support plate 7, thereby preventing the battery pack from shaking and falling off when moving the battery pack.

[0034] Reference Figure 1 and Figure 5 The auxiliary components include fixed plates 25 symmetrically fixed to both sides of the vehicle body 1. Cylinder 26 is fixedly connected to the top of each of the two fixed plates 25. A U-shaped block 27 is rotatably connected to the output end of cylinder 26. A wheel 28 is rotatably connected inside the U-shaped block 27. Cylinder 26 is electrically connected to controller 3.

[0035] After the battery pack is removed, the controller 3 can start the cylinder 26, which pushes the U-shaped block 27 to drive the wheel 28 down. At this time, the wheel 28 can contact the ground and make the vehicle body 1 away from the ground. According to the effect of friction, the device can be moved stably by pushing the vehicle body 1 through the wheel 28, which is easier and less strenuous, and greatly improves the practicality and convenience of the device.

[0036] The implementation principle of this embodiment of an auxiliary device for replacing a car battery is as follows: First, the device is pulled to one side of the bottom of the car. Then, the controller 3 starts the motor 10 to drive the threaded rod 11 to rotate. Since one end of the adjusting block 5 is threadedly connected to the threaded rod 11, the rotation of the threaded rod 11 will cause the adjusting block 5 to slide along the inner wall of the groove 9. At the same time, the end of the adjusting block 5 away from the threaded rod 11 slides on the guide rod 12 to limit the adjustment block 5 and prevent it from rotating. At this time, by adjusting the position of the adjusting block 5, the connecting plate 6 and the support plate 7 can be moved up and down until the top surface of the support plate 7 is in contact with the car. The bottom surface of the vehicle battery pack fits tightly. When the support plate 7 cannot reach the bottom of the battery pack, the controller 3 can activate cylinder 13. Since the output end of cylinder 13 is fixedly connected to one end of the support plate 7, when cylinder 13 extends, it pushes the support plate 7, causing the slider 15 to slide inside the groove 14, thereby pushing the support plate 7 forward until it is moved to the bottom of the battery pack. This greatly improves the practicality and convenience of the device and better adapts to different vehicle conditions. Then, motor 2 16 can be activated to drive gear 17 to rotate. Since both racks 19 mesh with gear 17, gear 1... When the support plate 7 rotates, it drives the two racks 19 to slide in opposite directions along the inner wall of the guide block 18. At this time, the racks 19 drive the two connecting blocks 20 to move, causing the two connecting blocks 20 to drive the two sliding plates 21 to slide along the inner wall of the guide groove 23. Simultaneously, the two sliding plates 21 drive the two clamping plates 22 to move closer to each other until the two clamping plates 22 are tightly attached to both sides of the battery pack. At this time, the two rubber anti-slip pads 24 can increase the friction between the clamping plates 22 and the support plate 7 and the battery pack, improve the clamping stability, prevent the battery pack from falling off, and ensure that the battery pack can stay firmly on the support plate 7, thereby preventing movement. When the battery pack is being moved, it may shake and fall off. Then, the battery pack can be manually removed and separated from the car. Finally, cylinder 26 is activated, pushing U-shaped block 27 to lower wheel 28. At this point, wheel 28 contacts the ground, lifting the car body 1 off the ground. Due to friction, pushing the car body 1 through wheel 28 allows the device to move stably, making it easier and less strenuous. This greatly improves the device's practicality and convenience. Therefore, during battery pack replacement, it effectively reduces the workload of staff, assists in battery pack replacement, eliminates the need for manual handling of the battery pack, reduces physical exertion, and effectively improves work efficiency.
