Description

A kind of battery pack cabinet of honeycomb core structures
Technical field
The utility model relates to battery pack packing case technical fields, and in particular to a kind of battery lodge of honeycomb core structures Body.
Background technique
As the factors such as environmental protection, the energy influence, electric vehicle obtains the increasingly favor of compatriots as new-energy automobile, either Electronic cycling or electric car, the weight of power battery all directly affects the performance of electric vehicle, and power battery is using It is easy to cause batteries caught fire, explosion, Most current batteries of electric automobile packet uses because the accidents such as colliding again in the process Sheet metal work welding forms, either metal plate punching, cast aluminium or aluminum profile splicing, all haves the shortcomings that different such as metal plates are spelled It is insufficient to weld cabinet intensity, and metal plate punching opening period is longer, die cost is high, cast aluminium tank thickness is larger, aluminum profile cost The problems such as higher, and that there is weight is big for above-mentioned tank material, and energy transmission cannot be blocked when colliding, be easy to cause case The battery pack in internal portion breaks down, or even the danger of kindling, explosion.For this purpose, the utility model provides a kind of honeycomb core structures Battery pack cabinet, reduce the weight of battery pack cabinet, improve battery pack cabinet intensity, while improving the items of battery pack cabinet Performance.
Summary of the invention
For above-mentioned Shortcomings, the utility model provides a kind of battery pack cabinet of honeycomb core structures, to solve battery Lodge body weight is big, and intensity is insufficient, energy absorption performance difference problem.For this purpose, the utility model provides the following technical solutions:
A kind of battery pack cabinet of honeycomb core structures, the battery pack cabinet include all around and the honeycomb of lower section Plate, the cellular board include honeycomb clamping plate and cellular sandwich, and the honeycomb clamping plate includes substrate, attaches hardening on substrate Layer attaches the dope layer on hardened layer and attaches the sticky glue-line under substrate, and the cellular sandwich includes by multiple six sides Body honeycomb core is formed by connecting.
Above-mentioned, the substrate is steel or aluminum profile.
Above-mentioned, the hexagonal honeycomb core is worked out by metal material silk screen.
Above-mentioned, the cellular sandwich two sides pass through the sticky glue-line clamping of honeycomb clamping plate by two pieces of honeycomb clamping plates It is fixed.
Above-mentioned, cellular board by welding or connects and fixes the battery pack cabinet two-by-two.
Above-mentioned, the hardened layer is nickel-chrome alloy layer.
The utility model has the beneficial effects that
The utility model structure is simple, and it is rationally novel to design, and battery pack cabinet uses honeycomb sandwich construction, effectively reduces Battery pack weight promotes battery energy density;By designing honeycomb plate structure, battery pack cabinet intensity is improved, and safety is good; Cellular board can shorten fabrication cycle by splicing, meet production capacity and promote demand, be full of air inside cellular board, be conducive to battery The holding of packet internal heat improves the service life cycle of battery pack.
Detailed description of the invention
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, below will be to institute in embodiment Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only to record in the utility model Some embodiments be also possible to obtain other drawings based on these drawings for those of ordinary skill in the art.

1- battery pack cabinet, 2- cellular board, 3- battery pack, 4- honeycomb clamping plate, 401- dope layer, 402- hardened layer, 403- Substrate, 404- viscosity glue-line, 5- cellular sandwich, 501- honeycomb core.
Specific embodiment
In order to make those skilled in the art more fully understand the scheme of the utility model embodiment, with reference to the accompanying drawing and Embodiment is described in further detail the utility model embodiment.
Referring to Fig.1 ~ 4, the battery pack cabinet of a kind of honeycomb core structures, battery pack cabinet 1 include all around and lower section Cellular board 2, cellular board 2 include honeycomb clamping plate 4 and cellular sandwich 5, honeycomb clamping plate 4 include substrate 403, attach substrate 403 on Hardened layer 402, attach hardened layer 402 on dope layer 401 and positioned at attach substrate 403 under sticky glue-line 404, honeycomb Sandwich 5 includes being formed by connecting by multiple hexahedron honeycomb cores 501, and hexagonal honeycomb core 501 is worked out by metal material silk screen, The damaged condition of battery pack cabinet 1 can be mitigated, while inhaling to greatest extent when battery pack is hit using this kind of structure Receive impact force.
Specifically, substrate 403 is steel or aluminum profile, which has certain thickness, and 5 two sides of cellular sandwich are by two pieces Honeycomb clamping plate 4, and fixed by 404 clamping of sticky glue-line of honeycomb clamping plate 4, it can guarantee the bulk strength of battery pack cabinet 1, And the weight of battery pack cabinet 1 can largely be mitigated using 4 structure of cellular sandwich, the case where same battery pack weight Under, in the case where can arranging that more battery packs or battery pack are constant, promote electric vehicle performance;The skeleton of honeycomb clamping plate 4 For substrate 403, have the hardened layer 402 of nickel-chrome alloy layer on substrate 403, further substrate 403 is reinforced, promotes bee The intensity of nest clamping plate 4, to guarantee the intensity of battery pack cabinet 1.
Specifically, the cellular board two-by-two 2 of battery lodge body 1 is fixed by the splicings form such as welding or clamping.
Mode described above describes the preferred embodiment of the utility model, undoubtedly, for the common of this field Technical staff can be with a variety of different modes to described without departing from the spirit and scope of the utility model Embodiment be modified.
