Description

Technical Field

[0001] The utility model relates to the field of power batteries, and in particular to a power battery box and a power battery. Background Art

[0002] Power batteries are the power source for tools, mostly referring to the batteries that power electric vehicles, electric trains, electric bicycles, and golf carts. Power batteries are the core components of new energy vehicles and an important direction for future energy transformation.

[0003] New energy vehicles are favored due to their energy-saving and environmentally friendly characteristics. They have been vigorously promoted in China, and every household has some understanding of new energy vehicles. The power battery is the power source that provides power for tools. In the traditional power battery installation and use method, the power battery is very afraid of being bumped, because the collision will cause the battery to deform and damage, and then cause accidents, spontaneous combustion, etc. At present, when a car collides with the front vehicle or rear-ends the rear vehicle during actual driving, the power battery box can easily be directly hit, resulting in damage to the power battery box, and then causing the power battery inside to be squeezed, resulting in spontaneous combustion, explosion, etc. Therefore, we have made improvements to this and proposed a power battery box and a power battery. Utility Model Content

[0004] The utility model aims to provide a power battery box and a power battery, which solves the problem that the existing power battery box and power battery have no collision protection for the power battery box during use, which easily and directly affects the safety protection of the power battery.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] A power battery box comprises a box and an anti-collision beam 1 and an anti-collision beam 2 arranged on both sides of the box, a buffer energy absorption structure is arranged inside the box, and a plurality of buffer energy absorption structures are connected end to end in sequence to form energy absorption protection; wherein, the anti-collision beam 1 and the anti-collision beam 2 are respectively connected to the buffer energy absorption structures on the two sides; the buffer energy absorption structure comprises an energy absorption side plate 1 and an energy absorption side plate 2, an energy absorption box is commonly connected between the energy absorption side plate 1 and the energy absorption side plate 2; a power dispersion plate is fixed on the energy absorption side plate 2.

[0007] As a preferred technical solution of the present application, a transmission part is extended from one end of the power dispersion plate toward the direction of the energy absorbing side plate.

[0008] As a preferred technical solution of the present application, the other end of the power dispersion plate is fixed to an energy absorbing side plate in the adjacent buffer energy absorbing structure.

[0009] As a preferred technical solution of the present application, an anti-collision beam 1 is located on the left side of the box body and is connected to a rod body 1, one end of which passes through the box body and is connected to a corresponding buffer energy absorption structure.

[0010] As a preferred technical solution of the present application, the second anti-collision beam is located on the right side of the box body and is connected to the second rod body, and the second rod body passes through the box body and is connected to the corresponding buffer energy absorption structure.

[0011] A power battery has battery slots distributed inside a box.

[0012] As a preferred technical solution of the present application, a power battery is embedded in the battery slot.

[0013] As a preferred technical solution of the present application, a battery cover is provided on the top of the box body for sealing and protecting the power battery.

[0014] In the scheme of this application:

[0015] 1. Through the buffer energy absorption structure, when the car is hit by a front or rear collision during driving, the first and second anti-collision beams can partially absorb the energy generated by the collision, thereby avoiding direct collision with the outside of the power battery box, which is conducive to maintaining the integrity of the power battery box and protecting the power battery inside;

[0016] 2. Through the buffer energy absorption structure, when the anti-collision beam 1 or the anti-collision beam 2 is hit, the collision energy will be transferred to the corresponding energy absorbing side plate 1 and the energy absorbing side plate 2 through the rod body 1 or the rod body 2. The energy absorbing side plate 1 or the energy absorbing side plate 2 hit by the energy will be deformed, thereby prompting the energy absorbing box inside to absorb the energy, further reducing the energy generated during the collision, so as to protect the power battery to the greatest extent;

[0017] At the same time, due to the sequential distribution of multiple buffer energy-absorbing structures, when a certain buffer energy-absorbing structure deforms and absorbs energy, the remaining energy will be dispersed step by step along the power dispersion plate to continuously consume the impact force after the collision, further improving the protection effect on the power battery.

[0029] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0030] like Figure 1-Figure 6 As shown, a power battery box and a power battery, comprising a box 1 and an anti-collision beam 1 2 and an anti-collision beam 2 3 arranged on both sides of the box 1, a buffer energy absorption structure 4 is arranged inside the box 1, and a plurality of buffer energy absorption structures 4 are connected end to end in sequence to form energy absorption protection, wherein the anti-collision beam 1 2 and the anti-collision beam 2 3 are respectively connected to the buffer energy absorption structures 4 on the two sides;

[0031] The buffer energy absorption structure 4 includes an energy absorption side plate 1 41 and an energy absorption side plate 2 42, an energy absorption box 43 is connected between the energy absorption side plate 1 41 and the energy absorption side plate 2 42, a power dispersion plate 44 is fixed on the energy absorption side plate 2 42, and both ends of the energy absorption side plate 1 41 and the energy absorption side plate 2 42 are fixedly connected to the corresponding side walls of the box body 1;

[0032] A transmission part 45 is extended from one end of the power dispersing plate 44 toward the energy absorbing side plate 1 41;

[0033] The other end of the power dispersing plate 44 is fixed to the energy absorbing side plate 41 in the adjacent buffer energy absorbing structure 4;

[0034] The anti-collision beam 2 is located on the left side of the box body 1 and is connected to a rod body 21, one end of the rod body 21 passes through the box body 1 and is connected to the corresponding buffer energy absorption structure 4;

[0035] The second anti-collision beam 3 is located on the right side of the box body 1 and is connected to the second rod body 31, and the second rod body 31 penetrates the box body 1 and is connected to the corresponding buffer energy absorption structure 4;

[0036] Both sides of the box body 1 are provided with grooves for corresponding rod bodies 1 21 and rod bodies 2 31 to pass through. When a collision occurs during the actual operation of the automobile, if the anti-collision beam 1 2 contacts the impact collision, the collision will be transmitted to the buffer energy absorption structure 4 through the anti-collision beam 1 2 and the rod body 1 21 thereon. In this process, the anti-collision beam 1 2 buffers the impact force once, and the remaining energy is transmitted to the energy absorption side plate 1 41 through the rod body 1 21. The energy absorption side plate 1 41 subjected to the impact force will prompt the energy absorption box 43 therein to absorb energy. When the energy absorption box 43 absorbs energy, it will deform so that the relative distance between the energy absorption side plate 1 41 and the energy absorption side plate 2 42 changes, so that the energy absorption side plate 1 41 will eventually partially contact the transmission part 45 to achieve the redispersion of the remaining impact energy, thereby realizing the sequential reduction of the impact energy through the sequential arrangement of multiple buffer energy absorption structures 4, and avoiding the impact force acting on the power battery 12 to the greatest extent, which is conducive to achieving the maximum protection of the power battery 12;

[0037] At the same time, if the anti-collision beam 2 3 contacts the outside first to cause a collision, the anti-collision beam 2 3 that is hit will initially disperse the energy, and then transmit it to the energy-absorbing side plate 2 42 on the buffer energy-absorbing structure 4 through the rod body 2 31 thereon, and the energy-absorbing side plate 2 42 absorbs the energy through the energy-absorbing box 43 thereon, and then disperses the energy step by step through the energy-absorbing side plate 1 41 to achieve energy absorption protection;

[0038] Through the cooperation between the anti-collision beam 1 2 and the anti-collision beam 2 3, the power battery inside the box body 1 can be protected synchronously at the front and rear sides, thereby improving the practicality of the power battery box in actual application.

[0039] A battery slot 11 is provided inside the box 1, and a power battery 12 is embedded in the battery slot 11. A battery cover 13 is provided on the top of the box 1 to seal and protect the power battery 12.

[0040] like Figure 2 and Figure 3 As shown, the battery slot 11 can be set according to the actual size of the power battery 12, and the size of the battery slot 11 can be slightly larger than the external size of the power battery 12, so that when the power battery 12 is assembled inside the box body 1 and is subjected to an external collision, there can be enough space for the energy-absorbing side plate 1 41 and the energy-absorbing side plate 2 42 to deform and absorb energy, thereby avoiding the deformed energy-absorbing side plate 1 41 and the energy-absorbing side plate 2 42 from conflicting with the power battery 12, thereby effectively ensuring the stable protection of the power battery 12.
