Description

Technical Field

[0001] The present invention relates to the technical field of new energy battery modules, and in particular to a high-safety new energy battery module. Background Art

[0002] New energy vehicles (NEVs) are vehicles that use unconventional automotive fuels as their power source, primarily encompassing new energy passenger vehicles and new energy commercial vehicles. The latter encompass all trucks and buses with nine or more seats, and are categorized as buses, trucks, semi-trailer tractors, incomplete bus vehicles, and incomplete truck vehicles. Compared to new energy passenger vehicles, new energy commercial vehicles typically offer greater design freedom regarding the spacing between their new energy batteries. New energy commercial vehicles (e.g., trucks and buses) have larger chassis structures, allowing for more space available for battery packs. Unlike passenger vehicles, which require a compact layout to save space, the design and structure of the battery modules can be customized, for example, in terms of size, shape, capacity, and functionality.

[0003] Regarding the commercial process of new energy commercial vehicles, since new energy battery modules generate a large amount of heat during use, they are currently often handled by relying on battery management systems combined with air cooling and liquid cooling. However, when an abnormal failure occurs in the battery module, the battery cell group inside the battery module will still generate a large amount of heat and the high temperature will be abnormal. There is a risk of combustion in a relatively short period of time. The existing technology will slow down the combustion by adding an independent fire extinguishing device to the outer shell of the new energy battery module, that is, the existing traditional layout is: battery module + independent cooling system + fire extinguishing device (such as its overall height is 600mm). If an integrated functional shell for new energy battery modules is designed, and the overall height of the newly designed integrated functional shell is 500mm (a decrease of 16.7% compared with the overall height of the existing technology), then on the basis of improving the functional integration of the new energy battery module, the safety of the new energy battery can also be improved.

[0004] To this end, we have designed a highly safe new energy battery module. Summary of the Invention

[0010] Preferably, the safety mechanism includes an L-shaped plate slidably connected to the inner wall of the cavity, the side wall of the L-shaped plate is rotatably connected to gear 2 through a movable frame, the inner wall of the cavity is slidably connected to a straight rack, the inner wall of the cavity is fixedly connected to a fixed rack, one end of the straight rack is fixedly connected to a piston, and the inner wall of the cavity is respectively embedded with a one-way air inlet pipe and a one-way air outlet pipe.

[0012] Preferably, the gear 2 is meshed with the spur rack, the gear 2 is meshed with the fixed rack, the piston and the cavity are sealed and slid, the top wall of the L-shaped plate is installed with a toothed belt, and the inner wall of the cavity is installed with a control valve.

[0013] Preferably, the conversion gear is meshed with a plurality of annular teeth, and the amplifying gear is meshed with a toothed belt.

[0014] Preferably, a protective airbag is provided on the inner side wall of the shell, and the protective airbag is in a U-shaped structure. The bottom side wall of the protective airbag is fixedly connected to the inner side wall of the shell, and the top side wall of the protective airbag is embedded and slidably with the inner side wall of the shell.

[0017] Compared with the existing technology, the advantages of the present invention are:

[0018] 1. When the battery pack generates heat normally during use, the protection mechanism will not be triggered to operate. When the battery pack is abnormally hot, the cylinder will eject and move rapidly. By setting up L-shaped racks, U-shaped racks and multiple cutters, cutter one and cutter two move quickly close together until they cut an adjacent wire. This prevents the battery cell from continuing to heat up due to circuit faults, which could lead to subsequent thermal runaway or even high-temperature fire, thereby improving the safety of the battery module.

[0019] 2. When the cylinder moves downward rapidly, the inner wall of the bottom of the chute on the side wall of the cylinder no longer provides upward support for the sealing plate. The sealing plate slides downward under the action of gravity until it contacts the inner wall of the bottom of the air vent, forming a sealed state inside the shell, isolating the air circulation and facilitating the subsequent reduction of the oxygen content inside the shell.

[0020] 3. Furthermore, by providing structures such as annular teeth, an L-shaped plate, and a fixed rack, the spur rack achieves a multiplied travel distance, enabling sealed sliding of the piston over multiple distances within a limited space. Air inside the housing is drawn into the cavity via a one-way air inlet pipe, while inert gas stored in the cavity is squeezed into the housing via a one-way air outlet pipe, thereby diluting the air inside the housing and reducing the oxygen content in the air, thereby slowing down the rate of high-temperature fires in the battery module.

[0021] 4. When the C-shaped rack moves to the end of its stroke, the ejector pin installed on the C-shaped rack will press against the adjacent squeeze switch. Then, the flame retardant filled in the protective airbag will be sprayed outward through multiple solenoid valves onto the side of the battery cell group, covering the surface of the battery cell group, isolating it from the air, achieving the effect of flame retardancy and fire extinguishing. At the same time, it can also absorb heat, reduce the temperature of the battery cell group, and improve the safety of the battery module. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Protection mechanism includes a protective mechanism slidably connected to the inner wall of the convex cavity 4 annular block 501 (such as Figure 2As shown), the inner wall of the annular block 501 is slidably connected to the cylinder 502, and the side wall of the cylinder 502 is fixed with a spring 1 506, and the other end of the spring 1 506 is fixedly connected to the bottom wall of the annular block 501, and the side wall of the cylinder 502 is fixed with a truncated cone block 510. The inner wall of the convex cavity 4 is provided with a groove 507, and the inner wall of the groove 507 is fixedly connected to the spring 2 503. One end of the spring 2 503 is fixedly connected to a wedge block 508, and the wedge block 508 is slidably connected to the inside of the groove 507. The top wall of the wedge block 508 is provided with a wedge hole 509, and the side wall of the annular block 501 is fixedly connected to the wedge rod 505 through the cross bar 504. The inner wall of the shell 1 is provided with a through hole, and the wedge rod 505 moves a distance inside the through hole and slides against the wedge hole 509. The inner wall of the shell 1 is provided with a sliding hole 702 (as shown Figure 3 As shown), an L-shaped rack 701 is fixedly connected to the side wall of the cylinder 502, and a gear 1 705 is rotatably connected to the inner wall of the housing 1 through a support frame 704. A cutter 1 703 is installed on the side wall of the L-shaped rack 701, and a �-shaped rack 707 is slidably connected to the inner wall of the housing 1. A cutter 2 706 is installed on the side wall of the �-shaped rack 707;

[0033] Safety mechanism, which reduces the oxygen content inside the housing 1 to slow down combustion;

[0034] The trigger mechanism provides the protection mechanism with self-starting power.

[0036] The side wall of the housing 1 is provided with a plurality of vent holes 803 (combined with Figure 7 and Figure 4 As shown in the figure, the air holes 803 are of rectangular structure, and each air hole 803 has a storage groove 801 on the top wall, and a sealing plate 802 is slidably connected to the inner wall of the storage groove 801. The sealing plate 802 and the side wall of the cylinder 502 are limited and slided, that is, the side wall of the cylinder 502 is provided with a plurality of sliding grooves (not shown in the figure), and the sealing plate 802 has a convex structure when viewed from top to bottom, and the raised portion of the sealing plate 802 is slidably connected to the sliding groove of the side wall of the cylinder 502. The sealing plate 802 has a certain dead weight and can slide downward freely when there is no external force. Then, when the cylinder 502 moves downward, the inner wall of the bottom of the sliding groove of the side wall of the cylinder 502 does not provide an upward support force for the sealing plate 802, and the sealing plate 802 slides downward under the action of gravity. When the sealing plate 802 and the inner wall of the bottom of the air hole 803 are in contact with each other, the cylinder 502 can still slide downward for a distance under the action of the sliding groove.

[0037] The safety mechanism includes a cavity 612 formed on the inner wall of the bottom of the housing 1. The cavity 612 is a convex structure cavity. The inner wall of the cavity 612 is slidably connected to an L-shaped plate 604 (combined with Figure 1 and Figure 6 As shown), the side wall of the L-shaped plate 604 is fixedly connected to a movable frame 605, the inner wall of the movable frame 605 is rotatably connected to a gear 2 606, the inner wall of the cavity 612 is slidably connected to a straight rack 608, the inner wall of the cavity 612 is fixedly connected to a fixed rack 614, one end of the straight rack 608 is fixedly connected to a piston 609, and the inner walls of the cavity 612 are respectively embedded with a one-way air inlet pipe 610 and a one-way air outlet pipe 611, and the end of the one-way air inlet pipe 610 away from the cavity 612 is arranged on the bottom side wall of the shell 1, and the end of the one-way air outlet pipe 611 away from the cavity 612 is arranged on the top side wall of the shell 1.

[0038] One end of the cylinder 502 away from the convex cavity 4 extends to the inside of the cavity 612, and the side wall of the end of the cutting cylinder 502 away from the convex cavity 4 is fixedly connected with multiple annular teeth 602. The inner wall of the cavity 612 is rotatably connected with a rotating rod, and the side wall of the rotating rod is staggered and fixedly connected with a conversion gear 603 and an amplifying gear 607.

[0039] Gear 2 606 is meshed with the spur rack 608 , gear 2 606 is meshed with the fixed rack 614 , the piston 609 and the cavity 612 are sealed and slidable, a toothed belt 601 is installed on the top wall of the L-shaped plate 604 , and a control valve 613 is installed on the inner wall of the cavity 612 .

[0040] The conversion gear 603 is meshed and connected with the plurality of annular teeth 602 , and the amplifying gear 607 is meshed and connected with the toothed belt 601 .

[0041] The inner wall of the housing 1 is provided with a protective air bag 901 (combined with Figure 1 and Figure 5 As shown), the interior of the protective airbag 901 is filled with inert gas, and the protective airbag 901 is in a U-shaped structure. The bottom side wall of the protective airbag 901 is fixedly connected to the inner wall of the shell 1, and the top side wall of the protective airbag 901 is embedded and slidably with the inner wall of the shell 1, that is, the top side wall of the protective airbag 901 is provided with a hard protrusion block, which is embedded and slidably in the inner wall of the shell 1.

[0042] The protective airbag 901 is filled with flame retardant, and a squeeze switch 903 is fixedly installed on the bottom wall of the protective airbag 901. Multiple solenoid valves 904 are installed on the bottom side wall of the protective airbag 901. Multiple solenoid valves 904 are electrically connected to adjacent squeeze switches 903. A push rod 902 is installed on the U-shaped rack 707. After the push rod 902 moves a certain distance, it will be squeezed against the squeeze switch 903. The protective airbag 901 is made of high-temperature resistant elastic material. When it is filled with inert gas, it will expand and stretch. When the solenoid valve 904 is opened, the protective airbag 901 will automatically shrink. At this time, the top side wall of the protective airbag 901 and the inner wall of the shell 1 slide.

[0043] The trigger mechanism includes multiple temperature sensors (not shown in the figure) installed on the side wall of the battery cell group 2, and an electromagnetic push rod 11 is installed on the inner wall of the convex cavity 4. The movable end of the electromagnetic push rod 11 is fixedly connected to the circular block 501, and the temperature sensor is electrically connected to the electromagnetic push rod 11 through the controller.

[0044] In the present invention, when the battery pack 2 generates heat normally during use, as the temperature of the battery pack 2 rises, under the action of the temperature sensor, the movable end of the electromagnetic push rod 11 drives the circular ring block 501 fixedly connected thereto to move downward for a distance. In this process, since the wedge block 508 and the frustum block 510 are in contact with each other, the cylinder 502 is in a stationary state, and the spring 1 506 is compressed to accumulate elastic potential energy, the wedge rod 505 is unable to drive the wedge block 508 to move a sufficient distance, and the protection mechanism will not be triggered in the normal operating temperature range. The circular ring block 501 moves downward a further distance until the battery pack 2 reaches an abnormally high temperature. At this time, the circular ring block 501 will drive the wedge rod 505 to move downward a certain distance through the cross bar 504, and then slide against the wedge hole 509, so that the wedge block 508 slides a sufficient distance away from the cylinder 502, and then the wedge block 508 no longer limits the adjacent frustum block 510. At this time, the spring 1 506 will quickly extend and convert the elastic potential energy into kinetic energy, so that the cylinder 502 will quickly eject downward for a certain distance.

[0045] During the rapid downward movement of the cylinder 502, the cylinder 502 will drive the L-shaped rack 701 fixed thereto to move downward synchronously, and the L-shaped rack 701 will drive the C-shaped rack 707 to slide in the opposite direction for a distance through the gear 1 705, thereby causing the L-shaped rack 701 to slide downward rapidly, while the C-shaped rack 707 slides upward rapidly, then the cutter 1 703 and the cutter 2 706 will continue to move closer and closer rapidly until an adjacent wire 3 is cut off, thereby avoiding the continuous heating of the battery cell due to circuit failure, thereby causing subsequent thermal runaway or even high-temperature fire, thereby improving the safety of the battery module.

[0046] When the cylinder 502 moves downward rapidly, the bottom inner wall of the chute on the side wall of the cylinder 502 no longer provides an upward support force for the sealing plate 802. The sealing plate 802 slides downward under the action of gravity until it contacts the bottom inner wall of the air vent 803, thereby forming a seal inside the housing 1. The cylinder 502 can still continue to move downward under the action of the chute provided on its side wall.

[0047] On the other hand, the multiple annular teeth 602 provided on the bottom side wall of the cylinder 502 will drive the conversion gear 603 meshed with it to rotate. By setting the transmission ratio of the conversion gear 603 and the amplifying gear 607, when the conversion gear 603 drives the amplifying gear 607 to rotate, the amplifying gear 607 can drive the L-shaped plate 604 to move a longer distance through the toothed belt 601 meshed with it, and then drive the movement of the mobile frame 605 through the L-shaped plate 604, so that the gear 2 606 rotatably connected on the mobile frame 605 can move in the horizontal direction and can move in the fixed rack 614. The piston 609 rotates under the action of the piston 609, so that the straight rack 608 obtains a further enlarged moving distance, thereby being able to achieve a sealed sliding of multiple times the distance of the piston 609 in a limited space. When the piston 609 slides in a sealed manner, the air inside the shell 1 will be drawn into the cavity 612 through the one-way air inlet pipe 610, and the inert gas stored in the cavity 612 will be squeezed into the shell 1 through the one-way air outlet pipe 611, thereby diluting the air inside the shell 1 and reducing the oxygen content in the air, thereby slowing down the speed of high-temperature fire in the battery module and improving the safety of the battery module.

[0048] When the C-shaped rack 707 moves to the end of its stroke, the push rod 902 installed on the C-shaped rack 707 will be pressed against the adjacent squeezing switch 903, and then the multiple solenoid valves 904 will be switched from the closed state to the open state. Then, the flame retardant filled in the protective airbag 901 will be sprayed outward through the multiple solenoid valves 904 to the side of the battery cell group 2, covering the surface of the battery cell group 2, isolating the air, achieving the effect of flame retardancy and fire extinguishing. At the same time, it can also absorb heat and reduce the temperature of the battery cell group 2.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
