Description
Technical Field
The utility model relates to an auto-parts technical field particularly relates to a power battery box for energy-absorbing anticollision vehicle.
Background
At present, electric vehicles are developed vigorously, a power battery is an energy storage component of the electric vehicles, from the accident statistics and investigation results of the electric vehicles in recent years, the power battery becomes the focus of safety accidents of the electric vehicles, in some collision accidents, the power battery is subjected to fire and even explosion due to extrusion damage, and serious threats are brought to the life and property safety of passengers.
Disclosure of Invention
The utility model aims at providing an automobile-used power battery box of energy-absorbing anticollision, this battery box not only can absorb the collision energy, also has stronger anti collision performance moreover, can promote the protection efficiency to electric automobile power battery by a wide margin.
In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides an automobile-used power battery box of energy-absorbing anticollision, includes battery box inner panel, battery box anticollision intermediate layer, battery box energy-absorbing intermediate layer, battery box planking, its characterized in that: the automobile anti-collision device is characterized in that the bottom of the inner plate of the battery box is detachably connected with an automobile chassis, the anti-collision interlayer of the battery box is fixedly connected with the front, the rear, the left and the right of the inner plate of the battery box, the energy-absorbing interlayer of the battery box is fixedly connected with the anti-collision interlayer of the battery box, and the outer plate of the battery box is fixedly connected with the energy-absorbing interlayer of the battery box.
Preferably, the battery box anti-collision interlayer is an interlayer which is composed of three I-shaped structures and has a hexagonal section.
Preferably, the energy absorption interlayer of the battery box is an interlayer with a hollow hexagonal section.
Compared with the prior art, the invention has the following beneficial effects:
1. the energy-absorbing interlayer with the hollow hexagonal section is arranged in the battery box, and through deformation of the interlayer, collision energy can be absorbed, and impact on the power battery is reduced.
2. The battery box is provided with the hexagonal anti-collision interlayer with the cross section formed by three I-shaped structures, the I-shaped structures have good compression resistance and impact resistance, and the I-shaped structures are deformed into the hexagonal structures to be used in the anti-collision interlayer, so that large impact energy can be resisted, the battery box is not deformed, the integrity of the power battery is ensured, and the occurrence of fire and explosion accidents of the power battery is reduced.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
figure 2 is the cross-sectional view of the energy-absorbing and anti-collision sandwich of the present invention.
In the figure: 1. a battery box inner plate; 2. a battery box energy absorption interlayer; 3. the anti-collision interlayer of the battery box; 4. and a battery box outer plate.
Detailed Description
The invention will be further explained with reference to the accompanying drawings: as shown in fig. 1-2, a power battery box for an energy-absorbing anti-collision vehicle comprises a battery box inner plate 1, a battery box anti-collision interlayer 3, a battery box energy-absorbing interlayer 2 and a battery box outer plate 4, and is characterized in that: the automobile anti-collision device is characterized in that the bottom of the battery box inner plate 1 is detachably connected with an automobile chassis, the battery box anti-collision interlayer 3 is fixedly connected with the four front, back, left and right surfaces of the battery box inner plate 1, the battery box energy-absorption interlayer 2 is fixedly connected with the battery box anti-collision interlayer 3, and the battery box outer plate 4 is fixedly connected with the battery box energy-absorption interlayer 2.
The anti-collision interlayer 3 of the battery box is an interlayer which is composed of three I-shaped structures and has a hexagonal section.
The energy absorption interlayer 2 of the battery box is an interlayer with a hollow hexagonal section.
The working principle is as follows: when collision happens, external impact force firstly contacts with the outer plate 4 of the battery box, then the energy-absorbing interlayer 2 with the cross section being a hollow hexagon can deform under the action of the impact force to absorb collision energy, after the energy-absorbing interlayer 2 deforms, the rest collision impact force can come to the anti-collision interlayer 3 with the cross section being a hexagon and formed by three I-shaped structures, the anti-collision interlayer 3 which is deformed into a hexagon by the I-shaped structures can resist larger impact force without deformation, and then the integrity of the power battery can be ensured, and fire or explosion accidents caused by extrusion damage are avoided.
The embodiment is only an illustration of the concept and implementation of the present invention, and is not a limitation, and the technical solution without substantial transformation is still within the protection scope under the concept of the present invention.
