DETAILED DESCRIPTION OF THE INVENTION

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Referring to Figures 1-6 , an adjustable protection device for a new energy vehicle battery pack, including a base 5. A plurality of protection boxes 4 are installed inside the base 5. The lower end of the protection box 4 is connected to a heat dissipation fan 6. The heat dissipation fan 6 adopts a high-efficiency and low-noise design. The shape and material of its fan blades are carefully designed to generate strong wind when rotating quickly, timely discharge the heat in the protection box 4, and at the same time reduce the noise generated during operation, providing a quiet environment inside the vehicle; An installation frame 10 is fixed inside the protection box 4. Heat absorption and reinforcement plates 15 are installed at the upper and lower ends of the installation frame 10. The heat absorption and reinforcement plates 15 are composed of an anti-collision surface plate 16, a medium fiber board 17, a fireproof and moisture-proof bottom plate 18, a heat absorption felt 19, and a rear installation plate 20 from outside to inside. Two installation clamping mechanisms are fixed on one side inside the installation frame 10. A buffer clamping mechanism is installed on the clamping mechanism. A battery body 11 is installed on the buffer clamping mechanism. A water cooling device is installed on one side of the installation frame 10. A support frame 8 is installed inside the base 5. A top plate 3 is installed at the upper end of the support frame 8. An explosion-proof plate 1 is installed at the upper end of the top plate 3. A sensor group is installed on the battery body 11. The anti-collision surface plate 16 is located at the forefront of the heat absorption plate. A decorative paint surface can be set on the front outer wall of it, which not only plays a beautiful role, but also can protect the anti-collision surface plate to a certain extent. A plurality of equally spaced sound transmission holes penetrate through the anti-collision surface plate. In the heat absorption plate, it can be analogized as holes with certain special functions, which may contribute to heat conduction or dissipation, and can initially buffer the impact force from the outside and protect the internal structure; The medium fiber board 17 is arranged at the rear end of the anti-collision surface plate. A plurality of sound absorption holes penetrate through it at equal intervals. For the heat absorption plate, it can be conceived as channels contributing to heat exchange. The medium fiber board has a certain strength and can further disperse the impact force and enhance the stability of the overall structure; The fireproof and moisture-proof bottom plate 18 is located at the rear end of the medium fiber board, which can prevent the outside moisture and flame from damaging the inside of the heat absorption plate, and can also assist in the stability of the structure to a certain extent and resist the deformation generated during impact; The heat absorption felt 19, as the key part of heat absorption, is located at the rear end of the fireproof and moisture-proof bottom plate. It can effectively absorb heat, and when being impacted, it has a certain elasticity and can play a buffering role to reduce the impact on the heat absorption function; The rear installation plate 20 is located at the rear end of the heat absorption felt and is used to install the heat absorption plate to a specific position. It can provide support for the entire heat absorption plate to ensure its stable operation after installation, and also participates in the overall anti-collision structure and works in coordination with other parts; The base 5 is provided with a mounting groove 7. The protection box 4 is installed in the mounting groove 7. Screws 9 are installed at the four corners of the base 5. The size of the mounting groove 7 is precisely adapted to the protection box 4, which can ensure that the protection box 4 is stably installed therein, avoiding displacement due to shaking during vehicle driving, thus affecting the safety of the battery pack; The sensor group includes a temperature sensor, a humidity sensor and a pressure sensor. The sensors have high precision and high reliability, and can monitor the temperature, humidity and pressure changes of the battery body 11 in real time and accurately, providing reliable data support for the intelligent control system; The water-cooling device includes a water-cooling circulation device 13 fixed on one side of the mounting rack 10. One end of the water-cooling circulation device 13 is connected with a coolant storage tank 14. A second mounting plate 12 is installed at one end of the water-cooling circulation device 13. A coolant circulation pipeline 25 is installed on one side of the second mounting plate 12. One end of the coolant circulation pipeline 25 is connected with the water-cooling circulation device 13. One side of the coolant circulation pipeline 25 corresponds to the battery body 11. The coolant circulation pipeline 25 is closely attached to the surface of the battery body 11, which can efficiently take away the heat generated by the battery body 11. The coolant storage tank 14 can store enough coolant to ensure the continuous operation of the water-cooling device; The explosion-proof plate 1 is successively composed of a nano-enhanced composite material substrate 21, an intelligent phase change material protection layer 22, a buffer energy-absorbing layer 23 and an electromagnetic shielding layer 24 from top to bottom. The nano-enhanced composite material substrate 21 uses nanotechnology to modify the fiber-reinforced composite material, adding nano-scale reinforcing particles such as nano-silica and carbon nanotubes in the fiber matrix. These nano-particles can be evenly dispersed in the fiber matrix, enhancing the interfacial bonding force between the fiber and the matrix and improving the strength and toughness of the substrate. Compared with the traditional fiber-reinforced composite material, the nano-enhanced composite material substrate has a 30%-50% improvement in impact resistance without changing the weight, and at the same time has better heat resistance and corrosion resistance; The intelligent phase change material protection layer 22 introduces an intelligent phase change material into the protection layer of the explosion-proof plate. The material is in a solid state at normal temperature. When encountering the high temperature generated by an explosion, it will quickly undergo a phase change and absorb a large amount of heat, thereby reducing the temperature on the surface of the explosion-proof plate. At the same time, the intelligent phase change material can also automatically adjust its physical properties according to the temperature change, becoming harder at high temperature and enhancing the impact resistance of the explosion-proof plate. In addition, the intelligent phase change material also has the function of adsorbing toxic gases and can effectively purify the harmful gases generated by the explosion; A buffer energy-absorbing layer 23 is added between the substrate and the protective layer. A porous foam material (such as polyurethane foam, aluminum foam, etc.) is used. The porous foam material has good energy-absorbing characteristics. When subjected to an explosion shock, it can absorb a large amount of energy through the compression deformation of the foam, reducing the damage of the explosion impact force to the substrate and the protective layer. At the same time, the buffer energy-absorbing layer can also play a role in sound insulation and heat insulation, further improving the comprehensive performance of the explosion-proof board; Electromagnetic shielding layer 24 For some places where electronic devices are concentrated, such as substations, communication machine rooms, etc., an electromagnetic shielding layer is added to the explosion-proof board. The electromagnetic shielding layer uses conductive fiber fabric or metal foil, which can effectively shield the electromagnetic pulse generated by the explosion and protect the electronic devices from interference and damage; The clamping mechanism includes two bearing plates 33 fixed at one end of the mounting frame 10. A sliding groove 27 is provided on one side of the bearing plate 33. A slider 28 is installed in the sliding groove 27. Two dampers 26 are fixed on one side in the sliding groove 27. One end of the two dampers 26 is commonly connected to one side of the slider 28. The damper 26 can provide a certain resistance when the slider 28 slides, slowing down the movement speed of the slider 28, thereby effectively buffering the vibration and impact during vehicle driving and protecting the battery body 11 from damage; The buffer clamping mechanism includes two springs 29 installed on one side of the slider 28. A moving block 30 is installed in the sliding groove 27. One end of the two springs 29 is connected to one side of the moving block 30. One end of the moving block 30 is connected to a connecting column 31. One end of the connecting column 31 penetrates through the side wall of the bearing plate 33 and extends to one side of the bearing plate 33. The lower ends of the two connecting columns 31 are commonly connected to a U-shaped clamping block 32. The upper end of the battery body 11 abuts against the U-shaped clamping block 32. The spring 29 has good elasticity and can automatically adjust the position of the U-shaped clamping block 32 according to the vibration situation during vehicle driving, ensuring that the battery body 11 is always firmly clamped, and at the same time further buffering the vibration and impact.

The intelligent control system real-time monitors the temperature, pressure, and humidity parameters of the battery pack through sensors distributed in various parts of the battery pack and the protection device; S2.

When abnormal conditions such as sensor failures and component damages are detected, it promptly issues an alarm signal and records the fault information for subsequent maintenance and troubleshooting. S5.
