Description

Technical Field

[0001] The present invention belongs to the technical field of battery installation structures, and specifically relates to a battery installation structure for new energy sanitation vehicles. Background Art

[0002] New energy sanitation vehicles use electric drive systems, reducing dependence on fuel, significantly reducing greenhouse gas emissions and air pollution. Electric sanitation vehicles operate with relatively low noise, which helps to improve the urban environment. The battery installation structure for new energy sanitation vehicles is usually a framework that provides support and protection for the battery. This framework not only supports the battery pack but also incorporates some important design considerations. The design of the framework ensures that the battery pack remains stable during vehicle operation, preventing damage caused by factors such as vibration and collision. It is usually customized according to the shape and size of the battery pack to effectively utilize the interior space of the vehicle. High-strength metal materials (such as aluminum alloy or steel) or composite materials are usually used to ensure its reliability under high-load conditions, guaranteeing the safe, effective, and durable operation of the battery in the vehicle.

[0003] A Chinese patent with the publication number CN116788020A discloses an installation structure for a new energy battery pack, including a housing. The interior of the housing is hollow, and two juxtaposed installation slots are provided on the side of the housing. Two installation frame components are symmetrically and movably connected inside the two installation slots. The installation frame component includes a concave plate, and a strip-shaped plate is fixedly connected to one side surface of the concave plate. First teeth are fixedly connected to the top and bottom of the side surface of the strip-shaped plate along its length direction. A linkage component is provided between the strip-shaped plates of the two opposite installation frame components to assist the two installation frame components to be inserted into or removed from the installation slots simultaneously. A middle seat is fixedly connected to the middle position of the bottom end surface of the groove of the concave plate, and a plurality of uniformly distributed T-shaped partitions are fixedly connected to both sides of the middle seat. Battery blocks are provided on both sides of the T-shaped partitions. In the present invention, the battery pack can be pushed out and the individual batteries can be pushed out in a staggered manner, facilitating the quick removal of the batteries by the staff.

[0004] In the actual use process of the existing battery installation structure for new energy sanitation vehicles, it is impossible to achieve quick limit installation of the battery, which appears to be somewhat limited. Tools are usually required to fix the position of the battery, increasing the complexity and time consumption of the installation process. Since additional fixing operations are required each time the battery is replaced and installed, this not only reduces work efficiency but may also affect the continuity and smoothness of the operation.

[0005] Therefore, the present invention provides a battery installation structure for new energy sanitation vehicles. Summary of the Invention

A compression plate 12 is fixedly installed at the bottom of the connecting plate 10. A driving assembly corresponding to the compression plate 12 is arranged inside the protective plate 5. A limiting assembly is arranged inside the placement groove 6. When using the battery installation structure for a new energy sanitation vehicle to fixedly support the power battery 7 used by the sanitation vehicle, an installation space is provided for the power battery 7 through the placement groove 6. The new energy sanitation vehicle is electrically connected to the connector 2 through a wire, thereby providing energy for the operation of the new energy sanitation vehicle and facilitating the new energy sanitation vehicle to perform operation to process garbage. Threaded holes corresponding to the through holes on the positioning plate 4 are arranged on the new energy sanitation vehicle. After using bolts to pass through the through holes and threadedly connect with the threaded holes, the position of the housing 1 will be positioned and installed through the positioning plate 4, so that it is positioned on the new energy sanitation vehicle. The top cover 3 can disperse the heat generated during the operation of the power battery 7 through the heat dissipation fins, improving the heat dissipation efficiency. When installing the power battery 7 assembly through the placement groove 6, after placing the power battery 7 inside the placement groove 6, the power battery 7 is supported and limited by the support plate 8. At the same time, the bottom of the power battery 7 is attached to the top of the negative pressure hole 9, so that the movement of the driving assembly will adjust the position of the support plate 8, and then drive the power battery 7 to enter the placement groove 6 for storage. At the same time, the negative pressure assembly and the limiting assembly move, and will limit the position of the power battery 7, thereby facilitating the rapid limiting installation of the power battery 7, improving the installation efficiency and the installation stability. The bottom of the battery installation structure for a new energy sanitation vehicle is protected by the protective plate 5, and when touching foreign objects, damage to the power battery 7 is avoided, affecting the use.

[0034] As Figure 7 and Figure 8As shown in the figure, the negative pressure assembly includes a negative pressure hole 9, an air extraction pipe 23, a sliding groove 24, and a negative pressure mechanism. The negative pressure holes 9 are arranged in an array inside the support plate 8. The air extraction pipe 23 is embedded inside the support plate 8 and is connected to the negative pressure holes 9. The sliding groove 24 is embedded inside the support plate 8. The negative pressure mechanism is arranged inside the sliding groove 24. The negative pressure mechanism extracts the air inside the negative pressure holes 9 through the air extraction pipe 23. When the support plate 8 moves downward, the movement of the negative pressure mechanism will cause the negative pressure holes 9 to generate negative pressure. Furthermore, the negative pressure holes 9 will limit the position of the power battery 7, improving the stability of the installation of the power battery 7 and avoiding accidental shaking, which may affect normal use.

[0035] As Figure 8 shown in the figure, the negative pressure mechanism includes a negative pressure groove 25, a piston block 26, a connecting rod 27, a driving spring 28, a limiting cylinder 29, and a connecting block 30. The negative pressure groove 25 is fixedly installed inside the sliding groove 24, and one end of the air extraction pipe 23 is connected to the negative pressure groove 25. The piston block 26 is arranged inside the negative pressure groove 25. One end of the connecting rod 27 is fixedly connected to the central position of the piston block 26. The limiting cylinder 29 is fixedly installed inside the negative pressure groove 25, and the connecting rod 27 passes through the limiting cylinder 29. The driving spring 28 is arranged around the connecting rod 27, and one end of the driving spring 28 is fixedly connected to the limiting cylinder 29. The connecting block 30 is fixedly installed at one end of the connecting rod 27. A limiting component is arranged inside the support plate 8. When the support plate 8 moves downward, the limiting component will pull the connecting block 30 to move. When the connecting block 30 moves, it will drive the connecting rod 27 to move smoothly. The limiting cylinder 29 will guide the connecting rod 27 to move smoothly. When the connecting rod 27 moves, it will drive the piston block 26 to move. When the piston block 26 moves, the air inside the negative pressure holes 9 will be extracted through the negative pressure groove 25 and the air extraction pipe 23. Furthermore, negative pressure will be formed inside the negative pressure holes 9 to limit the position of the power battery 7, thereby improving the stability of the installation of the power battery 7.

[0036] As Figure 4 and Figure 7 shown in the figure, the limiting component includes a towing rope 31 and an L-shaped pipe 32. The L-shaped pipe 32 is fixedly installed inside the support plate 8, and one end of the L-shaped pipe 32 is connected to the sliding groove 24. One end of the towing rope 31 is fixedly connected to the connecting block 30, and the other end of the towing rope 31 passes through the L-shaped pipe 32 and is fixedly connected to the placement groove 6. When the support plate 8 moves downward, since one end of the towing rope 31 is fixedly connected to the inner wall of the placement groove 6, when the support plate 8 moves downward and drives the negative pressure mechanism to move, one end of the towing rope 31 will pull the connecting block 30 to move. When the connecting block 30 moves, it will drive the piston block 26 to move through the connecting rod 27. Furthermore, the air inside the negative pressure holes 9 will be extracted through the negative pressure groove 25 and the air extraction pipe 23. Furthermore, negative pressure will be generated inside the negative pressure holes 9 to limit the power battery 7.

[0037] As Figure 4As shown in the figure, the driving component includes a threaded barrel 13, a movable groove 14, a threaded rod 15 and a driving motor 16. One end of the threaded barrel 13 is fixedly connected to the central position of the compression plate 12. One end of the threaded barrel 13 extends into the corresponding movable groove 14. The movable grooves 14 are arranged in an array inside the protective plate 5. The threaded rod 15 is threadedly connected inside the threaded barrel 13. The driving motor 16 is fixedly installed inside the movable groove 14, and one end of the threaded rod 15 is fixedly connected to the output end of the driving motor 16. The controller 33 controls the driving motor 16 to work. When the driving motor 16 works, it drives the threaded rod 15 to rotate. When the threaded rod 15 rotates, the position of the threaded barrel 13 moves. The threaded barrel 13 drives the compression plate 12 to move. At the same time, the connecting plate 10 drives the support plate 8 to move, thereby adjusting the position of the support plate 8 and adjusting the position of the supported power battery 7. When the compression plate 12 moves downward, the air inside the compression groove 11 is compressed. On the contrary, the output end of the driving motor 16 rotates in the reverse direction to reset the compression plate 12 and the support plate 8. When the compression plate 12 resets, the compressed air flows back. At the same time, when the support plate 8 resets, it pushes the power battery 7 to reset, thereby facilitating the replacement of the power battery 7.

[0038] As Figure 4 shown in the figure, an air duct 17 corresponding to the compression groove 11 is arranged inside the housing 1, and one end of the air duct 17 is communicated with the compression groove 11. When the compression plate 12 moves to compress the air inside the compression groove 11, the compressed air flows into the air duct 17. The compressed air flows to the inside of the sealing groove 19 through the air duct 17.

[0039] As Figure 4 and Figure 5 shown in the figure, the limiting component includes a strip-shaped groove 18, a sealing groove 19, a sliding plate 20 and a limiting plate 22. The strip-shaped groove 18 is embedded inside the housing 1 and is communicated with the placing groove 6. The sealing grooves 19 are symmetrically installed inside the strip-shaped groove 18, and the air duct 17 is communicated with the sealing groove 19. The sliding plate 20 penetrates through the sealing groove 19. The limiting plate 22 is arranged inside the placing groove 6, and one end of the sliding plate 20 is fixedly connected to the limiting plate 22. After the compressed air flows into the sealing groove 19, it pushes the sliding plate 20 to move. When the sliding plate 20 moves, it drives the limiting plate 22 to move synchronously. When the limiting plate 22 moves, it contacts and presses the power battery 7 inside the placing groove 6, thereby limiting and installing the position of the power battery 7, so that the power battery 7 is limited inside the placing groove 6 for use, improving the stability of installation.

[0040] As Figure 5As shown, a reset spring 21 is arranged in an array inside the strip-shaped groove 18, and the other end of the reset spring 21 is fixedly connected to the limiting plate 22. The reset spring 21 is located on one side of the strip-shaped groove 18. When the reset spring 21 resets, it can pull the limiting plate 22 back to its original position. After the limiting plate 22 resets, it no longer limits the power battery 7, so that the power battery 7 can be quickly replaced and used, improving the efficiency of replacing the power battery 7.

[0041] As Figure 2 shown, a controller 33 is arranged on the housing 1, and the controller 33 is electrically connected to the drive motor 16. The limiting plate 22 is made of rubber, and the drive motor 16 can be controlled to work through the controller 33.

[0042] Working principle: Firstly, when using the battery installation structure for new energy sanitation vehicles to fix and support the power battery 7 used in the sanitation vehicle, the placement groove 6 provides an installation space for the power battery 7. The new energy sanitation vehicle is electrically connected to the connector 2 through a wire, thereby providing energy for the operation of the new energy sanitation vehicle, facilitating the new energy sanitation vehicle to perform operation tasks to handle garbage. There are threaded holes corresponding to the through holes on the positioning plate 4 on the new energy sanitation vehicle. After using bolts to pass through the through holes and thread them with the threaded holes, the positioning plate 4 will position and install the shell 1, positioning it on the new energy sanitation vehicle. The top cover 3 can disperse the heat generated during the operation of the power battery 7 through the heat dissipation fins, improving the heat dissipation efficiency. When installing the power battery 7 components through the placement groove 6, after placing the power battery 7 inside the placement groove 6, the support plate 8 supports and limits the power battery 7. At the same time, the bottom of the power battery 7 fits with the top of the negative pressure hole 9. Control the driving motor 16 to work. When the driving motor 16 works, it will drive the threaded rod 15 to rotate. When the threaded rod 15 rotates, it will move the position of the threaded barrel 13. Through the threaded barrel 13, it will drive the compression plate 12 to move. At the same time, through the connecting plate 10, it will drive the support plate 8 to move, thereby adjusting the position of the support plate 8 and adjusting the position of the supported power battery 7, so that the power battery 7 completely enters the placement groove 6 for storage and installation. When the support plate 8 moves downward and drives the negative pressure mechanism to move, one end of the traction rope 31 will pull the connecting block 30 to move. When the connecting block 30 moves, it will drive the piston block 26 to move through the connecting rod 27. Then, through the negative pressure groove 25 and the air extraction pipe 23, the air inside the negative pressure hole 9 will be extracted, and thus negative pressure will be generated inside the negative pressure hole 9 to limit the power battery 7. When the compression plate 12 moves downward, the air inside the compression groove 11 will be compressed. The compressed air flow will enter the air delivery pipe 17. Through the air delivery pipe 17, the compressed air will flow into the sealing groove 19. The compressed air flow will enter the air delivery pipe 17. Through the air delivery pipe 17, the compressed air will flow into the sealing groove 19 to limit the position of the power battery 7. Thus, it is convenient to quickly limit the position of the power battery 7 for installation, improving the installation efficiency and the installation stability. The protection plate 5 protects the bottom of the battery installation structure for new energy sanitation vehicles. When touching foreign objects, it can prevent damage to the power battery 7 and affect its use.
