Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy plate technology, and in particular to an aluminum alloy battery tray. Background Technology

[0002] An aluminum alloy battery tray is a device used to fix and protect battery components. The relatively low density of aluminum alloy makes the battery tray lighter overall, which helps to reduce the overall weight of new energy vehicles and improve driving range.

[0003] The prior art discloses a battery tray, a power battery pack, and a vehicle (publication number: CN110190211A). The tray body includes a base plate, side beams, and several partitions. The side beams are arranged around the base plate and together with the base plate define the space for accommodating battery cells. The partitions are arranged on the base plate and divide the base plate into several areas for placing battery cells. Gas channels are formed inside the partitions and inside the side beams and are interconnected. Several air inlets are provided on the partitions, and at least one exhaust hole is provided on the side beams. The air inlets are used to guide the flame, smoke, or gas discharged from the battery cells into the gas channels, and the exhaust hole is used to discharge the flame, smoke, or gas in the gas channels.

[0004] Existing technologies effectively prevent flames, smoke, or gas emitted from individual battery cells from accumulating inside the battery pack. However, no protective measures are taken for the batteries inside the tray. When the bottom of the battery tray is scraped, it may cause deformation and damage to the battery tray. When the vehicle is involved in a side collision, the impact force acts directly on the side of the battery tray, which may cause the battery pack to deform or even cause the battery to spontaneously combust.

[0005] Therefore, those skilled in the art have provided an aluminum alloy battery tray to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an aluminum alloy battery tray, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An aluminum alloy battery tray includes: an aluminum alloy tray, wherein a partition and a limiting plate are welded and fixed inside the cavity of the aluminum alloy tray, the partition and the limiting plate being perpendicular to each other; a bottom plate, wherein a bottom plate is fixedly installed at the bottom end of the aluminum alloy tray for protecting the bottom end of the aluminum alloy tray; a side energy-absorbing assembly, wherein buffer plates are fixedly installed on both sides inside the cavity of the aluminum alloy tray, and the side energy-absorbing assembly is disposed between the buffer plates and the inner side of the cavity of the aluminum alloy tray for energy absorption protection in the event of a collision; and a protection assembly, wherein the protection assembly is disposed on the side of the buffer plates away from the side energy-absorbing assembly, and the protection assembly is used to protect the battery pack, the protection assembly including a ring, a push rod, and a push post, wherein the ring pushes the push post by moving the push rod.

[0009] According to the aluminum alloy battery tray, the partition and the limiting plate divide the cavity of the aluminum alloy tray into rectangular compartments for placing battery packs, and a protective plate is fixedly installed on the side of each rectangular compartment near the buffer plate.

[0010] According to the aluminum alloy battery tray, the bottom end of the aluminum alloy tray is provided with a reinforcing rib to increase the bottom rigidity and torsional resistance, and the partition is located below the reinforcing rib.

[0011] According to the aluminum alloy battery tray, the side energy-absorbing component includes a first hexagonal frame and a second hexagonal frame. The second hexagonal frame is smaller than the first hexagonal frame. The two sides of the first hexagonal frame and the second hexagonal frame are respectively fixedly connected to the aluminum alloy tray and the buffer plate.

[0012] According to the aluminum alloy battery tray, a connecting rod is fixedly connected between the outer wall of the second hexagonal frame and the inner wall of the first hexagonal frame.

[0013] According to the aluminum alloy battery tray, the protective plate and the buffer plate are parallel to each other. The protective assembly also includes a fixing post and a rectangular box. There are two rectangular boxes, and both rectangular boxes are fixedly installed on the side wall of the protective plate near the buffer plate.

[0014] According to the aluminum alloy battery tray, the ring has through holes, and the fixing piles pass through the ring through the through holes. The number of through holes corresponds one-to-one with the number of fixing piles. Two sets of second mounting plates are fixedly installed on the outer wall of the ring, and two sets of first mounting plates are fixedly installed on one end of the push rod. The two ends of the push rod are movably connected to the second mounting plates and the first mounting plates through pins. The push rod, the second mounting plates, and the first mounting plates are symmetrical around the ring. The push rod moves through the rectangular box, and multiple force-bearing plates are fixedly installed inside the rectangular box cavity. One end of the push rod inside the rectangular box cavity is tapered.

[0015] This utility model provides an aluminum alloy battery tray. It has the following advantages:

[0016] (1) By setting partitions and limiting plates inside the cavity of the aluminum alloy tray, it is convenient to limit the installation of the battery pack and improve the rigidity of the aluminum alloy tray. Setting partitions at the bottom of the aluminum alloy tray can protect the bottom of the aluminum alloy tray and prevent the aluminum alloy tray from being deformed and damaged by scratches. Buffer plates are fixedly installed on both sides inside the cavity of the aluminum alloy tray, and the side energy absorption components are set between the buffer plates and the inner side of the aluminum alloy tray cavity for energy absorption protection in the event of a collision, so as to prevent the battery from being damaged after the side of the aluminum alloy tray is damaged, which could lead to battery spontaneous combustion. By setting protective components, the battery is further protected, and the protection limit of the product is increased to meet the safety requirements of the vehicle.

[0017] (2) By setting the first hexagonal frame and the second hexagonal frame to be fixedly connected to the aluminum alloy tray and the buffer plate on both sides respectively, and the connecting rod is fixedly connected between the outer wall of the second hexagonal frame and the inner wall of the first hexagonal frame, when the side of the aluminum alloy tray is impacted, the first hexagonal frame and the second hexagonal frame deform. During the deformation process, the kinetic energy generated by the collision is converted into internal energy, thereby reducing the impact force of the impact.

[0018] (3) The ring is fixedly installed on one side of the protective plate by means of a fixed pile and a rectangular box. The fixed pile passes through the ring through the hole. When the impact occurs, the impact force pushes the ring to move through the pressure buffer plate. The second mounting plate is fixedly installed on the outer wall of the ring. The push rod is movably connected to the second mounting plate by a pin. The first mounting plate is fixedly installed at one end of the push column. The push rod is movably connected to the first mounting plate by a pin. So when the ring approaches the protective plate, the ring pushes the push column to move through the push rod. The push column moves to square the rectangular box. The force plate is fixedly installed in the cavity of the rectangular box. The movement of the push column causes multiple force plates to bend. During the deformation process, the kinetic energy is converted into internal energy, which further offsets the impact force and protects the battery pack behind the protective plate, ensuring the safety of the battery pack.

[0027] like Figure 1-6 As shown: An aluminum alloy battery tray includes: an aluminum alloy tray 10, in which a partition 11 and a limiting plate 13 are welded and fixed inside the cavity of the aluminum alloy tray 10, the partition 11 and the limiting plate 13 being perpendicular to each other; a bottom plate 12, on which the bottom end of the aluminum alloy tray 10 is fixedly installed to protect the bottom end of the aluminum alloy tray 10; a side energy-absorbing assembly 16, on which buffer plates 14 are fixedly installed on both sides inside the cavity of the aluminum alloy tray 10, the side energy-absorbing assembly 16 being disposed between the buffer plates 14 and the inner side of the cavity of the aluminum alloy tray 10, for energy absorption protection in the event of a collision; and a protection assembly 17, on which the buffer plates 14 are disposed away from the side energy-absorbing assembly 16, the protection assembly 17 being used to protect the battery pack, the protection assembly 17 including a ring 22, a push rod 26 and a push post 29, the ring 22 pushing the push post 29 by moving the push rod 26.

[0028] Specifically, by setting a partition 11 and a limiting plate 13 inside the cavity of the aluminum alloy tray 10, the battery pack can be installed in a limited position, and the rigidity of the aluminum alloy tray 10 is also improved. The partition 11 at the bottom of the aluminum alloy tray 10 can protect the bottom of the aluminum alloy tray 10 and prevent deformation and damage to the aluminum alloy tray 10 caused by scratches. Buffer plates 14 are fixedly installed on both sides inside the cavity of the aluminum alloy tray 10, and the side energy absorption component 16 is set between the buffer plate 14 and the inner side of the cavity of the aluminum alloy tray 10 for energy absorption protection in the event of a collision, so as to prevent damage to the battery after the side of the aluminum alloy tray 10 is damaged, which could lead to battery spontaneous combustion. By setting a protection component 17, the battery is further protected, and the protection limit of the product is increased to meet the safety requirements of the vehicle.

[0029] The partition 11 and the limiting plate 13 divide the cavity of the aluminum alloy tray 10 into rectangular compartments for placing battery packs. Each rectangular compartment is fixedly equipped with a protective plate 15 on the side near the buffer plate 14.

[0030] Specifically, by setting up partitions 11 and limiting plates 13, the cavity of the aluminum alloy tray 10 is divided into rectangular compartments for placing battery packs. Protective plates 15 are fixedly installed on the side of the rectangular compartments near the buffer plate 14 to facilitate the installation of the protective components 17. The protective components 17 protect the batteries behind the protective plates 15.

[0031] The bottom of the aluminum alloy tray 10 is provided with a reinforcing rib 18 to increase the rigidity and torsional resistance of the bottom end, and the partition 11 is located below the reinforcing rib 18.

[0032] Specifically, by setting reinforcing ribs 18 at the bottom of the aluminum alloy tray 10, the rigidity and torsional resistance of the bottom of the aluminum alloy tray 10 are further enhanced, providing better protection against scratches from below.

[0033] The side energy-absorbing assembly 16 includes a first hexagonal frame 19 and a second hexagonal frame 20. The second hexagonal frame 20 is smaller than the first hexagonal frame 19. The two sides of the first hexagonal frame 19 and the second hexagonal frame 20 are fixedly connected to the aluminum alloy tray 10 and the buffer plate 14, respectively. A connecting rod 21 is fixedly connected between the outer wall of the second hexagonal frame 20 and the inner wall of the first hexagonal frame 19.

[0034] Specifically, by setting the two sides of the first hexagonal frame 19 and the second hexagonal frame 20 to be fixedly connected to the aluminum alloy tray 10 and the buffer plate 14 respectively, and the outer wall of the second hexagonal frame 20 and the inner wall of the first hexagonal frame 19 to be fixedly connected by a connecting rod 21, when the side of the aluminum alloy tray 10 is impacted, the first hexagonal frame 19 and the second hexagonal frame 20 deform. During the deformation process, the kinetic energy generated by the collision is converted into internal energy, thereby reducing the impact force.

[0035] The protective plate 15 and the buffer plate 14 are parallel to each other. The protective assembly 17 also includes a fixing post 24 and a rectangular box 25. There are two rectangular boxes 25, and both rectangular boxes 25 are fixedly installed on the side wall of the protective plate 15 near the buffer plate 14. A through hole 23 is opened on the ring 22. The fixing post 24 passes through the ring 22 through the through hole 23. The number of through holes 23 corresponds one-to-one with the number of fixing posts 24. Two sets of second mounting plates 31 are fixedly installed on the outer wall of the ring 22. Two sets of first mounting plates 30 are fixedly installed on one end of the push column 29. The two ends of the push rod 26 are movably connected to the second mounting plates 31 and the first mounting plates 30 through pins. The push rod 26, the second mounting plates 31 and the first mounting plates 30 are symmetrical around the ring 22. The push column 29 moves through the rectangular box 25. Multiple force-bearing plates 28 are fixedly installed in the cavity of the rectangular box 25. One end of the push column 29 in the cavity of the rectangular box 25 is conical.

[0036] Specifically, the ring 22 is fixedly installed on one side of the protective plate 15 by means of a fixed stake 24 and a rectangular box 25. The fixed stake 24 passes through the through hole 23 and moves through the ring 22. When an impact occurs, the impact force pushes the ring 22 to move through the pressure buffer plate 14. A second mounting plate 31 is fixedly installed on the outer wall of the ring 22. The push rod 26 is movably connected to the second mounting plate 31 by a pin. One end of the push column 29 is fixedly installed with a first mounting plate 30. The push rod 26 is movably connected to the first mounting plate 30 by a pin. Thus, when the ring 22 approaches the protective plate 15, the ring 22 pushes the push column 29 to move through the push rod 26. The push column 29 moves to square the rectangular box 25. The force-bearing plate 28 is fixedly installed inside the rectangular box 25. The movement of the push column 29 causes multiple force-bearing plates 28 to bend. During the deformation process, kinetic energy is converted into internal energy, which further offsets the impact force and protects the battery pack behind the protective plate 15, ensuring the safety of the battery pack.

[0037] The working principle of the aluminum alloy battery tray of this application is as follows: By setting a partition 11 and a limiting plate 13 inside the cavity of the aluminum alloy tray 10, it is convenient to limit the installation of the battery pack and improve the rigidity of the aluminum alloy tray 10. The partition 11 at the bottom of the aluminum alloy tray 10 can protect the bottom of the aluminum alloy tray 10 and prevent deformation and damage to the aluminum alloy tray 10 caused by scratches. Buffer plates 14 are fixedly installed on both sides inside the cavity of the aluminum alloy tray 10. The side energy absorption component 16 is set between the buffer plate 14 and the inner side of the cavity of the aluminum alloy tray 10 for energy absorption protection in the event of a collision. By setting a first hexagonal frame 19 and a second hexagonal frame 13, the battery pack can be installed in a more secure manner. The two sides of the hexagonal frame 20 are fixedly connected to the aluminum alloy tray 10 and the buffer plate 14, respectively. The outer wall of the second hexagonal frame 20 is fixedly connected to the inner wall of the first hexagonal frame 19. When the side of the aluminum alloy tray 10 is impacted, the first hexagonal frame 19 and the second hexagonal frame 20 deform. During the deformation process, the kinetic energy generated by the collision is converted into internal energy, thereby reducing the impact force and preventing damage to the battery after the side of the aluminum alloy tray 10 is damaged, which could lead to battery spontaneous combustion. By setting the protective component 17, the battery is further protected, and the protection limit of the product is increased to meet the safety requirements of the vehicle.
