Description

Technical Field

[0001] The invention relates to the technical field of end plates, and in particular to an anti-deformation end plate aluminum profile for new energy vehicles. Background Art

[0002] The anti-deformation end plate aluminum profile used in new energy vehicles is an aluminum alloy material component specially designed for the battery tray or battery module of new energy vehicles. It is usually located at both ends of the battery tray or module, and the end plate aluminum profile is used to protect the battery of the new energy vehicle.

[0003] For example, publication number: CN218849647U discloses "a deformation-proof end plate aluminum profile for new energy vehicles", including a base plate; two first end plates, both of which are slidably connected to the upper end of the base plate, and both of which have second fixing grooves at their upper ends, and both of which have two concave grooves at their upper ends; two second end plates, both of which are slidably connected to the upper end of the base plate, and both side ends of the two second end plates are fixedly connected with convex blocks.

[0004] However, in the prior art, in order to ensure the anti-deformation ability of the end plate, the profile needs to have a higher strength. However, too high strength will lead to reduced toughness of the material, making the end plate prone to brittle fracture when impacted, resulting in the battery not being effectively protected. When a material with stronger toughness is used, its strength is lower, resulting in the expansion of the battery during discharge not being effectively restrained. When the battery expansion is not effectively restrained, the diaphragm will be subjected to great pressure and the diaphragm may be punctured or torn. If the diaphragm is damaged, the positive and negative electrodes will be in direct contact, causing an internal short circuit in the battery. At the same time, the capacity of the battery will gradually decay. The existing end plate aluminum profile is difficult to effectively restrain the expansion of the battery while providing sufficient anti-collision protection for the battery. Summary of the invention

[0005] The purpose of the present invention is to provide an anti-deformation end plate aluminum profile for new energy vehicles, so as to solve the problem proposed in the above background technology that in order to ensure the anti-deformation ability of the end plate, the profile needs to have a higher strength, but too high strength will lead to reduced toughness of the material, making the end plate prone to brittle fracture when impacted, resulting in the battery not being effectively protected. When using a material with stronger toughness, its strength is relatively low, resulting in the expansion of the battery during discharge not being effectively restrained. When the battery expansion is not effectively restrained, the diaphragm will be subjected to great pressure, and the diaphragm may be punctured or torn. Once the diaphragm is damaged, the positive and negative electrodes will directly contact, causing an internal short circuit in the battery, and the capacity of the battery will gradually decay. The existing end plate aluminum profile is difficult to effectively restrain the expansion of the battery while providing sufficient anti-collision protection for the battery.

[0010] Preferably, a plurality of No. 1 reinforcing ribs are arranged between the through hole and the No. 1 reinforcing plate, and the No. 1 reinforcing ribs are triangular in shape.

[0011] Preferably, a No. 2 reinforcing rib is fixedly connected inside the seamless protective frame, and the No. 2 reinforcing rib is cross-arranged inside the seamless protective frame.

[0012] Preferably, a fixing column is fixedly connected to the upper portion of the mounting base, and the fixing column is fixedly connected to the side surface of the seamless protective frame.

[0013] Preferably, the fixing column is fixedly connected to the anti-collision plate, and a second reinforcement plate is fixedly connected to the side surface of the fixing column.

Four anti-collision plates are provided outside the seamless protection frame, and the four anti-collision plates are interconnected by plugging the connecting protrusion and the connecting groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

At the same time, the feed-back energy-absorbing tube and the feed-back frame will produce feed-back deformation to absorb the kinetic energy of the impact, thereby reducing the kinetic energy of the impact on the surface of the anti-collision plate, and can fully protect the battery module inside the seamless protective frame.

[0018] 3. In the present invention, when the impact force applied to the anti-collision plate is too large, the shear force borne by the connection between the connecting protrusion and the connecting groove is the largest, and the connection between the connecting protrusion and the connecting groove is damaged first, and the feedback energy absorption is generated again, which further consumes the energy of the impact and fully protects the battery module inside the seamless protective frame.
