[0002] New energy batteries are more suitable for automotive use than traditional lead-acid, nickel-cadmium, and nickel-metal hydride batteries. More and more car manufacturers are choosing to use new energy batteries. When assembling new energy batteries on the vehicle floor, the batteries need to be placed inside the battery casing before further wiring and other operations are performed to complete the installation. In order to better protect the batteries, anti-collision devices are used.

A crossbar passes through the inner side of the sliding sleeve, and a first spring is sleeved on the outer surface of the crossbar. A locking structure is provided in the inner cavity of the inner protective frame.

[0006] As a preferred embodiment of the present invention, the locking structure includes a battery arrangement cavity, a through groove, a retaining groove, a recess, and a bolt groove. The battery arrangement cavity is located inside the inner protective frame. A through groove is provided on one end surface of the inner protective frame, and a retaining groove is connected to one side of the through groove. A recess is provided in the middle of the top of the inner protective frame, and a bolt groove is provided at the corner of the top of the inner protective frame.

[0008] As a preferred embodiment of the present invention, an adapter seat is fixedly installed at one end of the partition, and a third spring is fixedly connected to the inner cavity of the adapter seat. A stop bar is fixedly connected to the other end of the third spring, and an auxiliary sliding plate is sleeved on the outer side of one end of the stop bar.

[0009] As a preferred embodiment of the present invention, a sealing seat is provided at the bottom of the sealing cover plate, and a locking block is provided on the side wall of the sealing seat, and a positioning bolt passes through the corner of the sealing cover plate.

[0010] As a preferred embodiment of the present invention, the rotating rod and the protective plate are rotatably connected, and the protective plate is equidistantly distributed along the center point of the outer protective shell.

[0011] In a preferred embodiment of the present invention, the sliding sleeve is slidably connected to the crossbar via the first spring, and the sliding sleeve is rotatably connected to the rotating rod.

[0012] As a preferred embodiment of the present invention, the bolt grooves are equidistantly distributed along the center point of the inner protective frame, and the bolt grooves and the inner protective frame form an integrated structure.

[0013] As a preferred embodiment of the present invention, the rubber bumps are equidistantly distributed on the sidewall of the insulating pad, and the interior of the rubber bumps is made of rubber material.

[0014] As a preferred embodiment of the present invention, the stop bar is slidably connected to the adapter seat via the third spring, and the stop bar is symmetrically distributed along the vertical center line of the adapter seat.

[0015] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0016] 1. By combining the outer protective shell, inner protective frame, protective plate, and damper, the battery can be effectively protected in subsequent driving. This prevents the battery from being damaged by collisions or shaking during vehicle operation, thus affecting its normal lifespan. The protective shell effectively protects the inner protective frame. When the vehicle chassis is hit, the protective shell can effectively protect it from direct contact with the inner protective frame, preventing damage to the battery itself. The protective plate, together with the damper, provides a simple damping effect, thereby achieving the purpose of buffering and preventing collisions.

[0017] 2. By combining the set separator, second damper, second spring and insulating pad, the arranged battery body can be effectively protected. At the same time, the separated batteries can effectively prevent bumps and knocks. The insulating pad and rubber bump are made of flexible materials such as rubber, which not only serve the purpose of insulation, but also effectively protect the battery body, thereby improving the service life of the battery itself. Moreover, the entire separator can be disassembled. When the separator is damaged or the arranged batteries need to be replaced, you only need to disassemble the separator, which is convenient and quick, and has higher overall practicality.

[0018] 3. By combining the sealing cover, sealing seat, and protrusion structure, the inner protective frame can be effectively sealed, preventing dust and other impurities from entering the inner protective frame during battery use. Over time, this dust can corrode the battery surface or the positive and negative electrode contact points, affecting the flow of current. Since the sealing seat is made of rubber, it can seal the inner protective frame when it is engaged with the top opening of the inner protective frame. At the same time, the protrusion engages with the groove, and with the help of multiple positioning bolts, a tight connection between the sealing cover and the inner protective frame can be achieved. This not only makes it easy to disassemble but also provides a good sealing effect. Attached Figure Description

[0028] To make the technical means, creative features, 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.

[0029] Please refer to Figure 1 As shown, the present invention provides a battery anti-collision device for new energy vehicles, including an outer protective shell 1, an inner protective frame 2 provided on the inner side of the outer protective shell 1, and a sealing cover plate 3 distributed on the upper part of the inner protective frame 2. A reserved slot 4 is provided on the side wall of the outer protective shell 1. A heat-conducting plate 5 is provided at the bottom of the inner cavity of the outer protective shell 1, and a heat dissipation fin 6 is provided at the bottom of the heat-conducting plate 5. A protective plate 7 is distributed on the inner side of the outer protective shell 1, and a first damper 8 is provided in the middle section of the side wall of the protective plate 7. A rotating rod 9 is distributed on one side of the first damper 8, and a sliding sleeve 10 is connected to one end of the rotating rod 9. A crossbar 11 passes through the inner side of the sliding sleeve 10, and a first spring 12 is sleeved on the outer surface of the crossbar 11. A locking structure is provided in the inner cavity of the inner protective frame 2.

[0030] When in use, first place the battery inside the inner protective frame 2, then use the sealing cover 3 to seal the inner protective frame 2. After sealing, place the inner protective frame 2 inside the outer protective shell 1. After the whole assembly is completed, place the outer protective shell 1 at the bottom of the car and connect the power supply to the car's wiring harness via wires.

[0031] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, an inner protective frame 2 is provided on the inner side of the outer protective shell 1, and a sealing cover plate 3 is distributed above the inner protective frame 2. A reserved slot 4 is provided on the side wall of the outer protective shell 1. A heat-conducting plate 5 is provided at the bottom of the inner cavity of the outer protective shell 1, and a heat dissipation fin 6 is provided at the bottom of the heat-conducting plate 5. One end of the heat dissipation fin 6 extends to the outer side of the bottom of the outer protective shell 1, but the extension length is not too long. A protective plate 7 is distributed on the inner side of the outer protective shell 1, and a first damper 8 is provided in the middle section of the side wall of the protective plate 7. When the inner protective frame 2 is placed inside the outer protective shell 1, the protection... Plate 7 will be attached to the outer surface of the inner protective frame 2. A rotating rod 9 is distributed on one side of the first damper 8, and a sliding sleeve 10 is connected to one end of the rotating rod 9. The rotating rod 9 and the protective plate 7 are rotatably connected. The protective plate 7 is equidistantly distributed along the center point of the outer protective shell 1. The sliding sleeve 10 is slidably connected to the crossbar 11 through the first spring 12. The sliding sleeve 10 and the rotating rod 9 are rotatably connected. The crossbar 11 passes through the inner side of the sliding sleeve 10, and the first spring 12 is sleeved on the outer surface of the crossbar 11. The inner cavity of the inner protective frame 2 is provided with a locking structure.

[0032] Since the outer protective shell 1 is fitted onto the outside of the inner protective frame 2, and the outer protective shell 1 is engaged with the bottom of the car through the reserved slot 4, when the car base is bumped during driving, the object that collides will first contact the outer protective shell 1, thus effectively protecting the inner protective frame 2 and ensuring the safety of the battery pack inside the inner protective frame 2, achieving the purpose of anti-collision. When the inner protective frame 2 sways laterally inside the outer protective shell 1, the inner protective frame 2 will push the protective plate 7 connected to one side. Then, under the action of the lateral force of the inner protective frame 2, the protective plate 7 will push the rotating rod 9, which in turn will push the sliding sleeve 10, which is rotatably connected to its other end through the connecting ear. This causes the sliding sleeve 10 to slide laterally along the crossbar 11. When the sliding sleeve 10 slides laterally... When the device moves, the first spring 12 will deform accordingly. At the same time, the movement of the protective plate 7 will also squeeze the first damper 8. The combined effect of the deformation of the first spring 12 and the first damper 8 can achieve the purpose of buffering and protection, thereby preventing the inner protective frame 2 from shaking significantly during vehicle operation, which could affect the stability of the internal battery pack and cause wires to fall off. This improves the practicality of the entire device. Since the bottom of the inner cavity of the outer protective shell 1 is provided with a heat-conducting plate 5, and the heat-conducting plate 5 is attached to the bottom of the inner protective frame 2, the heat generated by the battery during operation can be transferred by the heat-conducting plate 5 and dissipated through multiple heat dissipation fins 6 evenly distributed at the bottom, thereby achieving the purpose of heat dissipation.

[0033] As a further implementation of this embodiment, such as Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the engaging structure includes a battery arrangement cavity 13, a through groove 14, a retaining groove 15, a recess 16, and a bolt groove 17. The battery arrangement cavity 13 is located inside the inner protective frame 2. One end surface of the inner protective frame 2 has a through groove 14, and one side of the through groove 14 is connected to the retaining groove 15. A partition 18 is provided inside the battery arrangement cavity 13, and a second damper 19 is fixedly installed on the side wall of the partition 18. One end of the second damper 19 is fixedly connected to an insulating pad 20, and the other side of the insulating pad 20 has rubber protrusions 21. The rubber protrusions 21 are equidistant from each other. The rubber protrusions 21 are equidistantly distributed on the side wall of the insulating pad 20 and are made of rubber. A second spring 22 is fixedly connected to one corner of the insulating pad 20. An adapter 23 is fixedly installed at one end of the partition 18 and a third spring 24 is fixedly connected to the inner cavity of the adapter 23. A stop bar 25 is fixedly connected to the other end of the third spring 24 and an auxiliary sliding plate 26 is sleeved on the outer side of one end of the stop bar 25. The stop bar 25 is slidably connected to the adapter 23 through the third spring 24 and the stop bar 25 is symmetrically distributed along the vertical center line of the adapter 23.

[0034] When assembling the battery pack, the separator 18 is first extended through the inner side of the through slot 14 and into the inner side of the inner protective frame 2. Simultaneously, one end of the separator 18 engages with a pre-drilled slot in the inner wall of the inner protective frame 2, achieving initial positioning of the separator 18. Then, the adapter 23 at the other end of the separator 18 engages with the inner side of the through slot 14, achieving positioning of the separator 18. At this time, the stop rod 25 is positioned on one side of the stop groove 15, so the lateral force applied to the stop rod 25 disappears. Subsequently, the reverse force generated by the deformation of the third spring 24 pushes the stop rod 25 in the opposite direction, thus inserting one end of the stop rod 25 into the inner side of the stop groove 15, thereby achieving positioning of the separator 18. The auxiliary sliding plate 26 is used to improve the stability of the stop rod 25 during lateral movement. Qualitatively, after the multiple separators 18 are assembled, the battery packs are placed in the divided battery arrangement cavities 13. The battery packs will laterally press the insulating pad 20, realizing the lateral movement of the insulating pad 20. At this time, the insulating pad 20 laterally presses the second damper 19 and the second spring 22. The combined reaction force generated by the deformation of the two can effectively prevent the battery pack from lateral shaking and improve the stability of the battery pack itself. At the same time, since the internal structure of the rubber protrusion 21 is made of rubber, the multiple rubber protrusions 21 can further protect the battery pack and prevent the outer surface of the battery pack from being damaged by friction between it and the insulating pad 20. The multiple battery packs are electrically connected by wires, and the inner side of the insulating pad 20 can be reserved with holes for the wires to pass through.

[0035] As a further implementation of this embodiment, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a groove 16 is provided at the top center of the inner protective frame 2, and a bolt groove 17 is provided at the top corner of the inner protective frame 2. The bolt grooves 17 are evenly distributed along the center point of the inner protective frame 2, and the bolt grooves 17 and the inner protective frame 2 form an integrated structure. A sealing seat 27 is provided at the bottom of the sealing cover plate 3, and a locking block 28 is provided on the side wall of the sealing seat 27. The internal structure of the sealing seat 27 is made of rubber material, and a positioning bolt 29 passes through the corner of the sealing cover plate 3.

[0036] When the battery pack is placed inside the inner protective frame 2, the sealing cover 3 is snapped into the top opening of the inner protective frame 2. At this time, the sealing seat 27 is snapped into the inner protective frame 2. When the two are fully snapped into place, multiple locking blocks 28 distributed equidistantly along the center point of the sealing seat 27 can be snapped into the inner side of the groove 16, realizing the initial connection between the two. Then, multiple positioning bolts 29 are inserted through the sealing cover 3 and extended into the inner side of the bolt groove 17. At this time, rotating the positioning bolts 29 can realize the threaded connection between the positioning bolts 29 and the bolt groove 17. After the connection is completed, the inner protective frame 2 can be sealed, achieving an effective dustproof and waterproof effect.

[0037] Specific working principle:

[0038] In use, the partition 18 is first extended through the inner side of the through slot 14 and into the inner side of the inner protective frame 2. Simultaneously, one end of the partition 18 engages with a pre-drilled slot in the inner wall of the inner protective frame 2, achieving initial positioning of the partition 18. Then, the adapter 23 at the other end of the partition 18 engages with the inner side of the through slot 14, achieving positioning of the partition 18. At this point, the stop rod 25 is positioned on one side of the stop groove 15, so the lateral force applied to the stop rod 25 disappears. Subsequently, the reverse force generated by the deformation of the third spring 24 pushes the stop rod 25 in the opposite direction, thus inserting one end of the stop rod 25 into the inner side of the stop groove 15, thereby achieving positioning of the partition 18. The auxiliary sliding plate 26 is used to raise the stop rod 25. To ensure stability during lateral movement, after the multiple separators 18 are assembled, the battery packs are placed in the divided battery arrangement cavities 13. The battery packs laterally compress the insulating pad 20, causing the insulating pad 20 to move laterally. At this time, the insulating pad 20 laterally presses against the second damper 19 and the second spring 22. The combined effect of the opposing forces generated by their deformation effectively prevents the battery pack from lateral swaying, improving the stability of the battery pack itself. Furthermore, since the internal structure of the rubber protrusions 21 is made of rubber, the multiple rubber protrusions 21 further protect the battery pack, preventing friction damage between the outer surface of the battery pack and the insulating pad 20. The multiple battery packs are electrically connected via wires. Furthermore, the inner side of the insulating pad 20 can be pre-drilled with holes for wires to pass through. After the battery pack is arranged, the sealing cover 3 is snapped into the top opening of the inner protective frame 2. At this time, the sealing seat 27 and the inner protective frame 2 are snapped into place. When the two are fully snapped into place, multiple locking blocks 28 evenly distributed along the center point of the sealing seat 27 can engage with the inner side of the groove 16, achieving a preliminary connection between the two. Then, multiple positioning bolts 29 are inserted through the sealing cover 3 and extended into the inner side of the bolt groove 17. At this time, rotating the positioning bolts 29 can achieve a threaded connection between the positioning bolts 29 and the bolt groove 17. After the connection is completed, the inner protective frame 2 can be sealed, achieving an effective dustproof and waterproof effect. Then, the inner protective frame 2 is placed on the outer side. The outer protective shell 1 is fitted onto the outer side of the inner protective frame 2, and is connected to the bottom of the car via a pre-drilled slot 4. Therefore, when the car's base is bumped during driving, the object first contacts the outer protective shell 1, effectively protecting the inner protective frame 2 and ensuring the safety of the battery pack within it. When the inner protective frame 2 sways laterally inside the outer protective shell 1, it pushes the protective plate 7 connected to one side. Under the lateral force of the inner protective frame 2, the protective plate 7 pushes the rotating rod 9, which in turn pushes the sliding sleeve 10, connected to its other end via a connecting ear. This causes the sliding sleeve 10 to slide laterally along the crossbar 11.When the sliding sleeve 10 slides laterally, it causes the first spring 12 to deform. Simultaneously, the movement of the protective plate 7 compresses the first damper 8. The combined effect of the deformation of the first spring 12 and the first damper 8 creates a buffering and protective force, preventing the inner protective frame 2 from shaking excessively during vehicle operation. This would affect the stability of the internal battery pack and cause wires to detach, improving the overall practicality of the device. Furthermore, since the bottom of the inner cavity of the outer protective shell 1 is equipped with a heat-conducting plate 5, which is attached to the bottom of the inner protective frame 2, the heat generated during battery operation can be transferred and dissipated through multiple evenly distributed heat dissipation fins 6 at the bottom, thus achieving heat dissipation.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
