Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a new energy vehicle battery pack and a new energy vehicle. Background Art

[0002] The battery pack of new energy vehicles is the core component of electric vehicles, responsible for storing electrical energy and providing power for the vehicle. The basic functions of the battery pack include energy storage, output of electrical energy to drive the motor, and energy management and protection through the battery management system. The battery pack is usually located in the center of the chassis in the vehicle to lower the center of gravity of the vehicle and provide protection. If the heat generated by the battery pack during the charging and discharging process cannot be effectively dissipated, the battery temperature will rise, affecting the energy density and cycle life of the battery. In addition to thermal runaway, electrical short circuits and mechanical damage to the battery pack may also cause safety accidents.

[0003] Existing new energy vehicle battery packs generally adopt the method of centrally fixing and arranging individual batteries in a matrix. When the battery pack is charging and discharging, due to factors such as high temperature weather or battery aging, the heat generated by the battery charging and discharging is relatively large. Sometimes a single battery may spontaneously ignite at high temperature, causing the risk of fire in the entire battery pack. Existing methods such as sensors or radiators are used to prevent battery spontaneous combustion at high temperature. Even if the battery is sensed to have high temperature, due to the lack of knowledge of battery fire prevention and fire extinguishing among some new energy vehicle owners, it is difficult to cool down the vehicle or extinguish the fire in time when a single battery spontaneously ignites at high temperature. Due to the lack of timely blocking and the installation of multiple groups of batteries in a matrix arrangement, a single battery may cause the fire to spread after spontaneous combustion, thereby causing the remaining batteries to burn. It is difficult to extinguish the fire in time when a single battery spontaneously ignites, resulting in great safety hazards and property losses.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original foundation. Summary of the invention

[0040] Furthermore, the closing component 10 includes a rack 101, which is mounted at the bottom of the trigger plate 7, and the bottom of the rack 101 is meshed with a flat gear 102, which is mounted at the bottom of the inner wall of the mounting box 1, and one side of the flat gear 102 is connected to a bevel gear set 103, one group of bevel gears in the bevel gear set 103 is mounted on one side of the flat gear 102, and another group of bevel gears in the bevel gear set 103 is mounted at the bottom of the inner wall of the mounting box 1, and one end of the other group of bevel gears in the bevel gear set 103 is mounted with a rotating rod 104, which is mounted at the bottom of the inner wall of the mounting box 1, and one end of the rotating rod 104 A bevel gear set 3 105 is installed, one of the bevel gears in the bevel gear set 3 105 is installed at one end of the rotating rod 104, and another group of bevel gears in the bevel gear set 3 105 is installed on the other side of the baffle 3.

After the battery 84 spontaneously ignites and pops out, the top of the installation box 1 is closed by the two sets of cover 1011 to prevent the smoke and flame generated by the previously spontaneously ignited battery 84 from emitting from the top of the installation box 1, thereby preventing damage to other equipment of the vehicle. At the same time, when the remaining batteries 84 do not spontaneously ignite, the two sets of cover 1011 are opened to form an air channel at the top of the installation box 1 to dissipate heat for multiple sets of batteries 84, thereby reducing the probability of spontaneous combustion caused by excessive temperature of the battery 84.

[0041] The present invention also discloses a new energy vehicle, which adopts the above-mentioned new energy vehicle battery pack.

[0042] Working principle: During the charge and discharge process of the battery pack, when one of the batteries 84 in the battery pack spontaneously ignites due to high temperature, the expanded graphite plate 85 expands in the cavity between the mounting frame 81 and the battery 84 after being heated, wrapping the battery 84 to achieve flame retardancy. Expanded graphite is a new type of refractory material that can expand at high temperatures to form a closed-cell structure with excellent fire resistance and heat insulation properties. At high temperatures, expanded graphite will expand to form a closed-cell structure. These pores can block the spread of flames, thereby preventing the spread of fire. In addition, the closed-cell structure of expanded graphite can also In order to reduce heat conduction and heat transfer, thus playing a role of heat insulation, the expanded graphite plate 85 expands when heated and pushes the push plate 87 to slide, and the push plate 87 slides and drives the slide bar 86 to slide synchronously, and the slide bar 86 slides and pulls the spring 88 through the mounting plate 870, and the slide bar 86 drives the wedge block 89 at one end to slide, and the wedge block 89 slides and pushes the longer part of one side of the card plate 812, and the card plate 812 slides under force and drives the elastic telescopic rod 3 811 to contract, and the card plate 812 slides and drives the shorter part on the other side to break away from the inner wall of the card hole 820;

[0043] When the shorter portion of the other side of the card plate 812 is out of contact with the inner wall of the card hole 820, the second elastic telescopic rod 82 is extended and pushes the mounting frame 81 to slide along the slide rail 5. While the mounting frame 81 slides, it approaches and pushes open the rotating plate 51, so that the rotating plate 51 rotates on the inner wall of the mounting box 1. While the rotating plate 51 rotates, it accumulates force on the torsion spring 50. While the mounting frame 81 slides, it drives the battery 84 to slide to the other side of the baffle 3, so that a single battery 84 can be separated from the multiple battery groups 84 after self-ignition, avoiding the spontaneous combustion of the remaining batteries 84 in the battery pack;

[0044] Similarly, after the battery 84 and the expanded graphite plate 85 that have spontaneously combusted are disassembled and replaced, the operator pushes the mounting frame 81 to slide in the opposite direction along the slide rail 5. While the mounting frame 81 slides, it pushes the elastic telescopic rod 2 82 to contract. At the same time, the spring 88 contracts and drives the slide bar 86 to slide in the opposite direction through the mounting plate 870. While the slide bar 86 slides, it drives the wedge block 89 to slide in the opposite direction. Under the extension of the elastic telescopic rod 3 811, the wedge block 89 slides and causes the card plate 812 to slide in the opposite direction. When the mounting frame 81 slides in the opposite direction along the slide rail 5 to reach the position, the card plate 812 slides in the opposite direction and drives the shorter part on the other side to contact the inner wall of the card hole 820 and restore the card connection state, completing the position limiting of the mounting frame 81. When the mounting frame 81 slides in the opposite direction along the slide rail 5, the mounting frame 81 is out of contact with the rotating plate 51, and the torsion spring 50 after storing the force releases the energy, driving the rotating plate 51 to rotate and reset.

[0045] When the mounting frame 81 slides, the mounting frame 81 drives the rack 96 at the bottom to slide synchronously. Under the meshing action of the rack 96, the rack 96 passes through the flat gear 95 and causes the flat gear 95 to rotate. When the flat gear 95 rotates, it drives the input end of the bevel gear set 94 to rotate synchronously. When the input end of the bevel gear set 94 rotates, it meshes with the output end of the bevel gear set 94 to rotate synchronously. When the output end of the bevel gear set 94 rotates, it drives the screw 92 to rotate synchronously. Under the rotation action of the screw 92, the piston disk 93 threadedly sleeved on the outer surface of the screw 92 slides in the direction of the screw 92. When the piston disk 93 slides, the perfluorohexanone stored in the liquid inlet barrel 91 is squeezed to the nozzle 98 through the one-way valve 97. Under the continuous squeezing action of the piston disk 93, the perfluorohexanone is sprayed out from the nozzle 98 to extinguish the mounting frame 81 passing through the bottom of the nozzle 98 and the self-ignited battery 84.

[0046] Similarly, when the mounting frame 81 slides in the reverse direction, the mounting frame 81 drives the rack 96 at the bottom to slide in the reverse direction synchronously, the rack 96 passes through the flat gear 95 and causes the flat gear 95 to rotate in the reverse direction, and the flat gear 95 rotates in the reverse direction while driving the input end of the bevel gear set 94 to rotate synchronously, and the input end of the bevel gear set 94 rotates while the output end of the meshing bevel gear set 94 rotates in the reverse direction, and the output end of the bevel gear set 94 rotates in the reverse direction while driving the screw 92 to rotate in the reverse direction, and under the reverse rotation of the screw 92, the piston disk 93 threadedly sleeved on the outer surface of the screw 92 slides in the reverse direction of the screw 92, and the piston disk 93 slides in the reverse direction while sucking the perfluorohexanone stored in the liquid storage tank 4 into the liquid inlet barrel 91 through the one-way valve 2 99 and the hard pipe, completing the circulation replenishment of the perfluorohexanone in the liquid inlet barrel 91;

[0047] As the mounting frame 81 slides, it gradually approaches and pushes the trigger plate 7. The trigger plate 7 slides under force and pushes the elastic telescopic rod 1 6 to contract. As the trigger plate 7 slides, it drives the rack 2 101 at the bottom to slide synchronously. Under the meshing action of the rack 2 101, the rack 2 101 meshes with the flat gear 2 102 to rotate when it slides. When the flat gear 2 102 rotates, it drives the input end of the bevel gear set 2 103 to rotate synchronously. When the input end of the bevel gear set 2 103 rotates, it meshes with the output end of the bevel gear set 2 103 to rotate synchronously. When the output end of the bevel gear set 2 103 rotates, it drives the rotating rod 1 104 to rotate synchronously.
