Description

Technical Field

[0002] As global energy shortages and environmental pollution become increasingly serious, new energy vehicles, especially electric vehicles, have been rapidly developed and popularized due to their clean and efficient advantages. In this context, batteries, as the heart of new energy vehicles, have a crucial impact on the performance of the entire vehicle due to their performance and safety. However, current new energy vehicle batteries have many safety hazards, especially under extreme conditions such as overheating, short circuit, and impact. Battery performance may drop sharply and even cause safety accidents such as fire and explosion, seriously threatening the safety of passengers and passers-by. The reason is that the chemical properties of batteries determine that they are very likely to generate heat under certain conditions, and this heat may be difficult to dissipate effectively due to internal and external factors of the battery, thereby causing battery explosion.

[0003] In order to reduce the safety accident rate of new energy vehicles, a device that can reduce the impact on new energy vehicle batteries is studied, which can not only ensure the safety of new energy vehicles, but also effectively prolong the service life of new energy vehicle batteries, thereby steadily increasing the sales of new energy vehicles and making consumers more willing to choose new energy vehicles. Therefore, it is necessary to involve a new energy vehicle battery protection structure in the existing new energy vehicle technology field. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Example 1

[0035] like Figures 1 to 4 As shown, it is a schematic diagram of a battery protection structure for a new energy vehicle according to a preferred embodiment of the utility model. The battery protection structure for a new energy vehicle according to this embodiment includes a protection bottom plate 10, and limit blocks 11 are fixedly assembled on both sides of the protection bottom plate 10. A new energy battery pack 12 is movably assembled on the protection bottom plate 10, and limit plates 13 are fixedly assembled on both sides of the new energy battery pack 12. The limit blocks 11 are directly opposite to the limit plates 13 and movably penetrate therethrough. A protection side plate 14 is fixedly assembled on the protection bottom plate 10, and a fixed slide bar 15 is fixedly assembled on the protection side plate 14. A movable slider 17 is movably assembled on the fixed slide bar 15, and the fixed slide bar 15 movably penetrates the movable slider 17. A buffer spring 16 is fixedly assembled on the protection side plate 14, and the other end of the buffer spring 16 is fixedly assembled with the movable slider 17, and the fixed slide bar 15 is located between the buffer spring 16. In the embodiment, mounting blocks 18 are fixedly assembled on both sides of the movable slider 17, and connecting rods 19 are movably assembled on the mounting blocks 18. Limiting grooves 20 are fixedly assembled on both sides of the protective side plates 14, and limiting rods 21 are fixedly assembled in the limiting grooves 20. Limiting sliders 23 are movably assembled on the limiting rods 21. The limiting sliders 23 are located in the limiting grooves 20, and a damping spring 22 is fixedly assembled in the limiting grooves 20. The other end of the damping spring 22 is fixedly assembled with the limiting slider 23. The limiting rod 21 is located in the damping spring 22 and connected to the damping spring 22. The other end of the connecting rod 19 is movably assembled with the limiting slider 23. An impact baffle 24 is fixedly assembled on the movable slider 17, and a fixed clamping block 25 is fixedly assembled on the impact baffle 24. A limiting clamping slot 26 is provided on the protective bottom plate 10, and the fixed clamping block 25 is movably connected with the limiting clamping slot 26.

[0036] Working principle: Align the limit block 11 on the new energy battery pack 12 with the limit block 11 on the protective bottom plate 10 to fix and assemble the new energy vehicle battery. When the outside world impacts the impact baffle 24, the movable slider 17 will squeeze the buffer spring 16 along the direction of the fixed slide rod 15. The elastic deformation of the buffer spring 16 will produce a certain buffer. At the same time, under the movement of the movable slider 17, the connecting rod 19 will be driven to move, so that the limiting slider 23 moves in the limiting groove 20, and squeezes the shock-absorbing spring 22 along the direction of the limiting rod 21, and performs a certain buffer under the elastic deformation of the shock-absorbing spring 22, thereby playing a buffering role for the new energy battery, reducing safety hazards, and extending the life of the new energy vehicle battery.

[0037] Example 2

[0038] like Figures 1 to 6 As shown, it is a structural schematic diagram of a new energy vehicle battery protection structure of another preferred embodiment of the utility model. During the driving process of the new energy vehicle, there will be a certain amount of shaking, which will cause the battery of the new energy vehicle to shake. Due to the chemical properties of the battery of the new energy vehicle, the shaking of the battery may cause certain damage to the battery of the new energy vehicle, and even a safety accident may occur. Therefore, on the basis of Example 1, the device is improved, and a driving shaft 27 is fixedly assembled at the bottom of the protective base plate 10, and a transmission gear 28 is fixedly assembled on the driving shaft 27. A limiting guide rail 32 is fixedly assembled at the bottom of the protective base plate 10, and a transmission rack 29 is movably assembled on the limiting guide rail 32. The transmission gear 28 and the transmission rack 29 are toothed. One end of the transmission rack 29 is fixedly assembled with a mounting beam 30, and a fixed clamping block 31 is fixedly assembled on the mounting beam 30. The fixed clamping block 31 is located at both ends of the new energy battery pack 12.

[0039] Working principle: After the new energy battery is fixedly assembled on the protective base plate 10, the drive shaft 27 is started to drive the transmission gear 28 to rotate. The transmission gear 28 and the transmission rack 29 are toothed so that the transmission rack 29 moves along the direction of the limiting guide rail 32, so that the transmission racks 29 move toward each other, thereby driving the fixed clamping block 31 on the mounting beam 30 to clamp the new energy battery pack 12, thereby fixing the new energy battery, preventing the new energy battery from shaking itself and causing damage to the battery itself, thereby reducing safety risks.
