Abstract
The utility model discloses a fixed structure of a battery pack in a shell. The fixed structure comprises the battery pack and the metal shell, and further comprises a bracket. The bracket is provided with elastic devices. The battery pack is arranged on the bracket. The elastic devices are positioned outside the bracket, and contact the metal shell. By the bracket, the battery pack can be conveniently arranged, and the fixed structure of the battery pack is secure and reliable in assembly. Simultaneously, the battery pack can be vibrated in the running of the vehicle after being arranged on a vehicle, and the elastic devices have a certain vibration-proof function, so that the structure of the battery pack is kept secure.
Description
Technical field
The utility model relates to battery, the battery pack assembling structure of saying so exactly and being used for electric motor car.
Background technology
The battery assembling of electric motor car is normally carried out the back with battery pack and is wrapped thick foam of one deck or rubber blanket all around, then battery pack is filled in metal shell with strength by force.Bubble silk floss or rubber blanket can cushion the impact of metal shell to battery; But the difficulty and the Material Cost of assembling have been increased like this; And foam or rubber blanket itself have certain insulation effect; Battery heat radiation has been caused obstruction, and the foam anti-flammability is than plastic cement difference, the fail safe of battery has been stayed hidden danger.
Summary of the invention
Based on this, the purpose of the utility model provides the fixed structure of a kind of battery pack in shell, and the structure of this fixed structure is firm, and assembling is reliable; And has antihunt action.
Another purpose of the utility model provides the fixed structure of a kind of battery pack in shell, and this fixed structure is easy to assembly, and cost is low.
For achieving the above object, the utility model is to realize like this.
The fixed structure of a kind of battery pack in shell; This fixed structure includes battery pack, metal shell; It is characterized in that said fixed structure also includes support, and said support has elastic device, battery pack is arranged on the support; Elastic device is positioned at the outside of support, and contacts with metal shell.Through support, be convenient to install battery pack, also make the fixed structure of battery pack firm, assembling is reliable, simultaneously, after battery pack is installed in vehicle, has vibrations in the vehicle ', and elastic device has certain antihunt action, keeps the structure of battery pack firm.
Said support, its outside has a plurality of elastic devices.
Said elastic device, its both sides have fluting, are convenient to elastic device and metal shell and carry out resilient engagement.
Further, said elastic device is optimized for and is arranged at block tongue outstanding on the support, and an end of block tongue is fixed on the support, and outstanding and elasticity perk are then yearned in the outer end.
Above-mentioned block tongue, the outer end of its elasticity perk has the inclined plane, is convenient to contact with shell, can produce cushioning effect.
Above-mentioned block tongue, its outer end have a plurality of wavy surfaces or groove face, the frictional force during with increase block tongue and housing contacts.
Said elastic device, itself and metal shell carry out interference fit.
Said support and elastic device adopt plastics or plastic material to make usually, can cut down finished cost, and improve the installation effectiveness of battery pack.
Therefore, the utility model improves the fixed structure of battery pack in shell, and what make battery pack and shell combines more firmly, and assembling is reliable, and elastic device also has antihunt action simultaneously, helps protecting battery pack.
And the utility model is simple in structure, is convenient to realize, and is easy to make, with low cost, can be widely used in the battery pack assembling of electric motor car.

Fig. 2 is the cross sectional representation of mode shown in Figure 1.
Fig. 3 is the structural representation of support.
Fig. 4 is the structural representation of the elastic device of the utility model enforcement.

Embodiment
Below, shown in accompanying drawing, the practical implementation of the utility model is elaborated.
Fig. 1, shown in Figure 2, the battery pack 1 of leaning on support 2 fixedly to assemble, the elastic device 3 that relies on design on support 2, to protrude has played buffering and radially fixing effect after being fitted into battery metal shell 4.
Support 2 is when design size; Except that protrusion elastic device 3; Other part overall dimension is unified; Monolateral minimizing 0.3-1mm on the inner cavity size basis of metal shell 4 with the monolateral interference 0.2-0.6mm of metal shell 4 inner chambers, makes elastic device 3 and metal shell 4 form interference fit on the projection of the elastic device 3 of protrusion and the overall dimension.
Elastic device 3 on the support 2 is distributed in all directions of support 2, is convenient to support 2 and forms fit structure firm and that have cushioning effect with metal shell, and concrete structure such as Fig. 3 show.
The structure of concrete elastic device 3, like Fig. 4 and shown in Figure 5, elastic device 3 is outstanding tab-like structure, its both sides fluting 5, groove width 0.5-2mm, dark 5-15mm.Elastic device 3 one ends are fixed on the support 2, and the outer end yearning is stretched out.
Elasticity of extension device 3 outer ends on support 2 are equipped with guiding surface 6 and arc transition face on battery pack assembly direction both sides.
Compare tradition and adopt the mode of filling auxiliary material, this mode adopts plastic production with support 2 and elastic device 3, makes assembling more simple, and plastic material fatigue strength is higher than foam, rubber elastomeric material, and its life-span is higher, and cost is also lower simultaneously.
In the time of will packing metal shell 4 into the semi-finished product battery group 1 that support 2 assemblings are accomplished; Under the effect of lower inclined plane 6 on the elastic device 3 of protrusion on the support 2; The axial limit that pushes away is converted into power radially; Because of fluting 5 reason is arranged, make the projection of elastic device 3 can be, thereby make battery pack 1 metal shell 4 of under certain thrust, packing into towards internal strain.Battery pack 1 is packed into behind the metal shell 4 fully; Because support 2 is more, the resilience force after its elastic device 3 strains works to metal shell 4 together, uses battery pack 1 very stably to be fixed in the metal shell 4; Even in the vehicle ' process, vibrations are arranged; Also the effect because of elastic device 3 plays cushioning effect to shaking force, can not injure electric core, has guaranteed the trouble free service of battery.
In a word, the above is merely the preferred embodiment of the utility model, is not the scope that is used for limiting the utility model embodiment.Be that all equalizations of being done according to the utility model claim change and modification, all in the claim of the utility model.
