Abstract
The invention discloses a novel battery box structure. The novel battery box structure comprises a battery box shell and a battery box cover, wherein the battery box shell comprises a bottom wall, a plurality of side walls which extend from the bottom wall and surround the bottom wall and a storage cavity which is collectively formed by the bottom wall and the side walls, the battery box cover is in a trapezoid structure, and the inner side of the battery box shell is provided with a battery pack fixing plate; and one side of a battery box is provided with a U-shaped cavity, and air enters the battery box through the U-shaped cavity and is used for radiating the heat of the battery box. By adopting the novel battery box structure, the phenomenon such as the battery damage caused by the heating of the battery in the application process can be solved, the temperature of a battery pack can be effectively balanced, the battery box is locally reinforced, the weight of the battery box is technically reduced, the utilization rate of the material is increased while the overall rigidness and strength are reinforced, and the cost is reduced.
Description
technical field:
The present invention relates to a kind of battery case structure, especially relate to a kind of for the novel battery box structure on electric automobile.
background technology:
Battery case is for holding battery pack and the lead-in wire that is connected outside and battery.
On market, conventional battery case is rectangular frame structure, and frame, underframe use section bar welding, and build is large, and structural strength is low, and cost is high.In normal battery use procedure and charge and discharge process, battery-heating phenomenon cannot be avoided, and heat build-up can cause battery life to reduce for a long time, and hydraulic performance decline directly increases user's use cost.
summary of the invention:
In sum, the object of this invention is to provide a kind of novel battery case structure, for solving at present at battery use procedure battery-heating and battery being caused to the phenomenon of loss.It can form air pipeline in battery case, effectively the temperature of battery pack is carried out to balance.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is:
A kind of novel battery box structure, it comprises battery case housing and battery case case lid, the host cavity jointly forming around some sidewalls of diapire with by diapire and sidewall that battery case housing comprises diapire, extends from diapire, battery case case lid is trapezium structure, wherein, be provided with battery pack fixed head in battery case housing inner side.
Further, described battery pack fixed head is provided with hole.
Further, described hole forms the slot of the described battery pack of installing.
Further, described battery case is provided with U-shaped cavity in a side.
Further, battery case housing is connected by hexagon flange bolt with case lid.
The invention has the beneficial effects as follows: battery case is carried out to part and strengthen, and carry out technique loss of weight, in ensureing that integral rigidity, intensity are strengthened, improved stock utilization, reduce costs.The cavity body structure of a side forms air pipeline simultaneously, is conducive to the temperature balance control to battery pack.
brief description of the drawings:
Fig. 1 is battery case structural representation of the present invention;
Fig. 2 is battery pack fixed plate structure schematic diagram of the present invention;
Fig. 3 is U-shaped cavity body structure schematic diagram of the present invention.
embodiment:
Below in conjunction with drawings and embodiments, the present invention is further detailed explanation.
The three-dimensional exploded view of a kind of novel battery box structure as depicted in figs. 1 and 2, it comprises battery case housing 1 and battery case case lid 2, the host cavity jointly forming around some sidewalls of diapire with by diapire and sidewall that battery case housing 1 comprises diapire, extends from diapire, battery case case lid 2 is trapezium structure, is provided with battery pack fixed head 3 in battery case housing inner side.
Battery pack fixed head 3 carries out part to battery case and strengthens, and carries out technique loss of weight, in ensureing that integral rigidity, intensity are strengthened, has improved stock utilization, reduces costs.
Battery pack fixed head 3 is welded on the inside of battery case housing, be strip structure, on battery pack fixed head 3, there are some holes, for placing battery group fixing, between battery pack fixed head 3 and its fixed head facing mutually, be connected by short slab, also porose on short slab, short slab is used for separate batteries group and strengthens the bulk strength of battery pack fixed head 3, thereby strengthens the structural strength of whole battery case.
As shown in Figure 3, be provided with U-shaped cavity body structure in a side of battery case, the two ends up and down of cavity are connected by hexagon flange bolt with battery case housing and case lid respectively.The rear and front end of U-shaped cavity 4 is hatch frame, in electric automobile traveling process, air enters battery case by U-shaped cavity 4, and flow through from U-shaped cavity 4, increase the Air Flow in battery case, battery pack is dispelled the heat, prevent because the intensive heat accumulation that causes of battery affects battery life, improve the strength and stiffness of battery case, increased the effective time of battery, extending battery life.
