Abstract
The utility model discloses a battery box, which comprises a box body and a cover body covered on the box body. The box body comprises an outer box body and a lining body. The outer box body comprises a bottom wall and four sidewalls extended from the bottom wall. The lining body is a frame body which is formed by sequentially connecting four side plates with vent holes end to end. An interlayer is formed between the outer box body and the lining body. Compared with the prior art, the battery box has the advantages that: a double-layer structure design is adopted, and an outer layer structure completely isolates the inside of the battery box from the outside, so that the battery box is explosion-proof, dustproof and waterproof; in addition, radiating fin structures are arranged on the outer surfaces of the sidewalls of the outer box body, so that heat produced by a battery pack in the battery box is easily dissipated.
Description
[technical field]
The utility model relates to a kind of casing, relates in particular to the battery case that a kind of suitable electric automobile, electric bus are used.
[background technology]
Battery case is a vitals of electric automobile, electric bus; The battery case structure Design is directly connected to the trouble free service situation of battery pack in the casing; And traditional battery case comprises casing basically and is fastened on the lid on the casing; Casing comprises that base plate reaches upwardly extending two pairs of four blocks of side plates parallel to each other around base plate, contains series-parallel battery pack in the casing.
The maximum weak point of the battery case of this kind design is: battery pack is installed in the vehicle of running at high speed, because some faults inevitably take place in jolting of vehicle; As because of connecting insecure opening circuit between the cell, What is more, when certain cell generation internal short-circuit; Other batteries of parallel connection just can carry out reverse charging to this fail battery with it, thereby the temperature of fail battery is risen rapidly, cause battery explosion; The air-flow that blast produces just can be washed battery case open; At this moment, air outside just can get in the battery case fast, and too high temperature also has air-breathing; Cause the vehicle spontaneous combustion, the safety of personnel, property is brought great hidden danger.
In view of above drawback, be necessary to provide a kind of new battery case to overcome above-mentioned defective in fact.
[utility model content]
The purpose of the utility model is to overcome above-mentioned defective, and a kind of good performance of heat dissipation that has is provided, and can waterproof, anti-riot, corrosion-resistant safe battery case.
The technical problem of the utility model is to realize by following technical scheme: a kind of battery case; It comprises that casing and lid are connected to the lid on the casing; Wherein, said casing comprises outer case and inner lining body, and outer case comprises diapire and the sidewall that around diapire, extends; Inner lining body is four frameworks that the side plate that offers ventilation hole is in turn connected to form from beginning to end, forms interlayer between said outer case and the inner lining body.
Preferably, the outer surface of said outer case sidewall is provided with heat radiating fin structure, and the outer case side wall inner surfaces is provided with first reinforcement that extends to diapire from end face.
Preferably, the interlayer between said outer case and the inner lining body is provided with the pad frame that central authorities are provided with opening.
Preferably, the bottom surface of said outer case diapire is provided with second reinforcement of parallel distribution in the longitudinal direction, on Width, is provided with two parallel and slide blocks that be installed on movable pulley.
Preferably, install the accepting box that has or not the bottom on the said lid, said accepting box and lid are combined into Main Control Tank.
Preferably, after said cover cap was connected to casing, box house was sealing state.
Preferably, be assembled with battery pack in the said inner lining body, ventilation hole is arranged at the corresponding position of inner lining body two opposite sides plate.
Preferably, after said cover cap is connected to casing, be filled with non-combustion-supporting property gas in the casing.
Preferably, said non-combustion-supporting property gas is nitrogen.
Preferably, said casing and lid are processed by aluminum alloy materials.
Compared to prior art, the utlity model has following advantage:
1) battery case of the utility model is owing to have the double-decker design; And layer structure is inner isolated fully with the external world with battery case; Therefore; Even the battery case internal temperature is too high, air or non-combustion-supporting property gas limited in the casing can not kept the inner spontaneous combustion of battery case yet, have guaranteed the person and the property safety of driving.
2) because layer structure is inner isolated fully with the external world with battery case, so rainwater and the dust that in the vehicle ' process, produces also can't get in the Battery case.
3) because the outer surface of outer case sidewall is provided with heat radiating fin structure, so the heat that battery pack produces in the battery case also very easily leaves.

[embodiment]
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described further.
Extremely shown in Figure 5 like Fig. 1, a kind of battery case 100, it comprises that casing 10 and lid are connected to the lid 20 on the casing.
Inner lining body 12 is the framework that four blocks of side plates that offer ventilation hole 121,122 head and the tail are in turn connected to form, and forms interlayer between outer case 11 and the inner lining body 12, and said interlayer is provided with the pad frame 171 that central authorities are provided with opening.In order to form heat dissipation channel, aforementioned ventilation hole 121 is arranged at the corresponding position of inner lining body 12 two opposite sides plates 122 usually.
Because the battery pack of installing is too heavy in the battery case 100; Hope to reduce the weight of entire cell case simultaneously again; Therefore, the material of battery case casing 10 is selected lightweight and the big material (the utility model aluminium alloy material) of intensity usually for use, as a rule; In order to guarantee the bearing strength of battery case; Second reinforcement 18 of parallel distribution also can be set on the length direction of the bottom surface of the outer case diapire 13 of battery case, consider the convenience of carrying simultaneously, usually two parallel and slide blocks 19 that be installed on movable pulley can be set on Width.
The roughly rectangular shape of lid 20, it is fixed together with screw and casing 10, installs the accepting box 30 that has or not the bottom on the lid 20, and said accepting box and lid are combined into Main Control Tank.
During assembling, earlier inner lining body 12 is fixed in the outer case 11, again the battery pack after the connection in series-parallel is installed in the inner lining body 12, at last lid 20 lids are connected on the casing 10.Like this, casing 10 inside just can be sealing state, under nature, only have a spot of air in the casing 10.Because casing 10 inside are sealing state,, the battery case 100 of the utility model gets into so can preventing rainwater, dust.In addition, casing 10 comprises outer case 11 and inner lining body 12, this double-decker design; Even battery case 100 internal temperatures are too high, air or non-combustion-supporting property gas limited in the casing 10 can not kept battery case 100 inner spontaneous combustions yet, simultaneously; Double-decker; Can guarantee that battery pack in that slight explosion time takes place, can not destroy this enclosed construction, thereby guarantee the person and the property safety of driving.
A kind of battery case of the utility model; Be not restricted to described in specification and the execution mode; Therefore for the personnel of familiar field, can easily realize additional advantage and modification; So under the situation of the spirit of the universal that does not deviate from claim and equivalency range and limited and scope, the examples shown that the utility model is not limited to specific details, representational equipment and illustrates here and describe.
