[0002] As global attention to environmental protection and sustainable development continues to grow, new energy vehicles, as a key means of transportation to reduce carbon emissions and lower dependence on traditional fossil fuels, are experiencing unprecedented development opportunities. With their high efficiency, environmental friendliness, and energy-saving advantages, new energy vehicles are gradually becoming the mainstream development direction of the automotive market.

[0003] As the core power source of new energy vehicles, the performance of the battery pack directly determines the vehicle's range, power output and overall safety.

When the pressure sensor detects abnormal pressure changes, it determines that there may be a problem with the battery placement status.

[0025] 4.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] Reference Figure 1-6 An adjustable new energy vehicle battery pack protection device includes a base 5, a plurality of protection boxes 4 are installed in the base 5, and a cooling fan 6 is connected to the lower end of the protection box 4. The cooling fan 6 adopts a high-efficiency and low-noise design. The shape and material of the fan blades are carefully designed to generate strong wind force when rotating rapidly, thereby discharging the heat in the protection box 4 in time and reducing the noise generated during operation, thereby providing a quiet environment in the vehicle.

[0042] A mounting frame 10 is fixed in the protective box 4, and heat-absorbing reinforcement plates 15 are installed at the upper and lower ends of the mounting frame 10. The heat-absorbing reinforcement plates 15 are composed of an anti-collision panel 16, a medium-density fiberboard 17, a fire-proof and moisture-proof bottom plate 18, a heat-absorbing felt 19 and a rear mounting plate 20 from the outside to the inside. Two mounting clamping mechanisms are fixed on one side of the mounting frame 10, and the clamping mechanism is equipped with a buffer clamping mechanism. The buffer clamping mechanism is equipped with a battery body 11. A water cooling device is installed on one side of the mounting frame 10, and a support frame 8 is installed in the base 5. The upper end of the support frame 8 is equipped with a top plate. 3. A first mounting plate 2 is mounted on the upper end of the top plate 3, an explosion-proof plate 1 is mounted on the upper end of the first mounting plate 2, a sensor group is mounted on the battery body 11, and an anti-collision panel 16 is located at the front end of the heat absorbing plate. The outer wall of the front end can be provided with a decorative paint surface, which not only plays an aesthetic role, but also can protect the anti-collision panel to a certain extent. A plurality of equally spaced sound-transmitting holes are passed through the interior of the anti-collision panel, which can be compared to holes with certain special functions in the heat absorbing plate, which may help conduct or dissipate heat, can initially buffer the impact force of the outside world, and protect the internal structure;

[0043] The MDF board 17 is arranged at the rear end of the anti-collision panel. There are multiple sound-absorbing holes equidistantly penetrated inside. For the heat-absorbing board, it can be considered as a channel that helps heat exchange. The MDF board has a certain strength and can further disperse the impact force and enhance the stability of the overall structure.

[0044] The fireproof and moisture-proof bottom plate 18 is located at the rear end of the MDF board to prevent external moisture and flames from damaging the interior of the heat absorbing board. It can also help stabilize the structure to a certain extent and resist deformation caused by impact.

[0045] The heat-absorbing felt 19 is a key part of heat absorption and is located at the rear end of the fireproof and moisture-proof bottom plate. It can effectively absorb heat and has a certain elasticity when it is hit, which can play a buffering role and reduce the impact of the impact on the heat absorption function.

[0046] The rear mounting plate 20 is located at the rear end of the heat absorbing felt and is used to install the heat absorbing plate to a specific position. It can provide support for the entire heat absorbing plate to ensure that it can work stably after installation. It also participates in the overall anti-collision structure and cooperates with other parts.

[0047] The base 5 is provided with a mounting groove 7, and the protective 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 protective box 4, which can ensure that the protective box 4 is firmly installed therein and prevent displacement due to shaking during driving of the vehicle, thereby affecting the safety of the battery pack;

[0048] The sensor group includes a temperature sensor, a humidity sensor, and a pressure sensor. The sensors are highly accurate and reliable, and can accurately monitor the temperature, humidity, and pressure changes of the battery body 11 in real time, providing reliable data support for the intelligent control system.

[0049] The water cooling device includes a water cooling circulation device 13 fixed to one side of the mounting frame 10, one end of the water cooling circulation device 13 is connected to a coolant storage tank 14, one end of the water cooling circulation device 13 is mounted on a second mounting plate 12, and one side of the second mounting plate 12 is mounted on a coolant circulation pipeline 25, one end of the coolant circulation pipeline 25 is connected to 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, and can efficiently remove the heat generated by the battery body 11. The coolant storage tank 14 can store sufficient coolant to ensure the continuous operation of the water cooling device;

[0050] The explosion-proof panel 1 is composed, from top to bottom, of a nano-reinforced composite substrate 21, an intelligent phase-change material protective layer 22, a buffering energy-absorbing layer 23, and an electromagnetic shielding layer 24. The nano-reinforced composite substrate 21 utilizes nanotechnology to modify fiber-reinforced composite materials, adding nano-scale reinforcing particles such as nano-silicon dioxide and nano-carbon tubes to the fiber matrix. These nanoparticles can be evenly dispersed in the fiber matrix, enhancing the interfacial bonding between the fiber and the matrix and improving the strength and toughness of the substrate. Compared to traditional fiber-reinforced composite materials, the nano-reinforced composite substrate has a 30%-50% improvement in impact resistance while maintaining the same weight, and also offers improved heat and corrosion resistance.

[0051] The intelligent phase change material protective layer 22 introduces intelligent phase change material into the protective layer of the explosion-proof panel. The material is solid at room temperature. When it encounters the high temperature generated by the explosion, it will rapidly undergo phase change, absorbing a large amount of heat, thereby reducing the temperature of the surface of the explosion-proof panel. At the same time, the intelligent phase change material can also automatically adjust its physical properties according to temperature changes, becoming harder at high temperatures, thereby enhancing the impact resistance of the explosion-proof panel. In addition, the intelligent phase change material also has the function of adsorbing toxic gases, which can effectively purify the harmful gases generated by the explosion;

[0052] The buffering energy absorbing layer 23 is added between the base plate and the protective layer. It is made of porous foam material (such as polyurethane foam, aluminum foam, etc.). The porous foam material has good energy absorption properties. When subjected to explosion impact, 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 base plate and the protective layer. At the same time, the buffering energy absorbing layer can also play a role in sound insulation and heat insulation, further improving the comprehensive performance of the explosion-proof panel.

[0053] Electromagnetic shielding layer 24 For places where electronic equipment is concentrated, such as substations and communication rooms, an electromagnetic shielding layer is added to the explosion-proof panel. The electromagnetic shielding layer is made of conductive fiber fabric or metal foil, which can effectively shield the electromagnetic pulses generated by the explosion and protect the electronic equipment from interference and damage;

[0054] The clamping mechanism includes two supporting plates 33 fixed to one end of the mounting frame 10. A slide groove 27 is provided on one side of the supporting plate 33. A slider 28 is installed in the slide groove 27. Two dampers 26 are fixed to one side of the slide groove 27. One end of the two dampers 26 is connected to one side of the slider 28. The dampers 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 the vehicle's driving and protecting the battery body 11 from damage.

[0055] The buffer clamping mechanism includes two springs 29 installed on one side of the slider 28, and a moving block 30 is installed in the slide groove 27. One end of the two springs 29 is connected to one side of the moving block 30, and one end of the moving block 30 is connected to a connecting column 31. One end of the connecting column 31 passes through the side wall of the supporting plate 33 and extends to one side of the supporting plate 33. The lower ends of the two connecting columns 31 are commonly connected to a U-shaped block 32. The upper end of the battery body 11 is in contact with the U-shaped block 32. The spring 29 has good elasticity and can automatically adjust the position of the U-shaped block 32 according to the vibration conditions during the vehicle driving process, ensuring that the battery body 11 is always firmly clamped, while further buffering vibration and impact.
