Abstract
The utility model provides an absorber of a lithium battery pile; one surface of the absorber is convexly provided with a peripheral sleeve lip which can limit the position of the battery; a radiating portiforium is arranged on the absorber. The absorber of a simple structure, excellent structure stability and good radiating effect, and can be implemented easily and used conveniently; moreover, the absorber is firm and durable, flame retardant and insulated.
Description
[technical field]
The utility model relates to the lithium battery group, especially a kind of lithium battery group vibration absorber that guarantees that cell safety uses.
[background technology]
Along with electrokinetic cell is widely used in the electric motor car field, the assembling of electrokinetic cell has become an important technology problem in this field.Be voltage and the power that reaches the motor requirement, great majority adopt the series-parallel connected mode of more piece (referring to Fig. 1) between the battery in the power battery pack.Electric motor car can produce vibration at work, move, and vibration, mobile might causing produce collision and friction between battery and the battery pack box body, and battery meeting leakage, short circuit influence the safe operation of power battery pack when serious.General way is a cotton pad of putting the cotton shape that there is glue on some two sides at the wall of battery pack box body, but this way has two big shortcomings: 1, cotton pad is not corrosion-resistant, unavoidably can be wet by the rain and burnt by the sun when electric motor car is worked in the open air, cotton pad can rot, the space of battery case the inside just can become big relatively like this, battery inside rocks, and battery container has electricity, may be short-circuited with the can collision; 2, cotton pad is inflammable thing, and lithium battery has the danger of exploding and firing, in case produce the blast of catching fire, the combustion-supporting meeting of cotton pad makes consequence even more serious.
[utility model content]
Technical problem to be solved in the utility model provides a kind of lithium battery group vibration absorber that guarantees that cell safety uses.
For solving the problems of the technologies described above, the utility model provides a kind of vibration absorber of lithium battery group, comprises base plate, but the one side of base plate convexes with the outer race lip of limiting battery position, offers the perforate of heat radiation on the base plate.During use, the upper end of each battery that can be in battery pack fastens a vibration absorber, lower end pressing one flat plate, vibration absorber and fixes with dull and stereotyped, perhaps the lower end of the battery of each in battery pack fastens a vibration absorber, upper end pressing one flat plate, vibration absorber and dull and stereotyped fixing, and perhaps the two ends up and down of the battery of each in battery pack respectively fasten a vibration absorber respectively, two vibration absorbers are fixed.The outer race lip can encase battery, and battery is solid in certain scope by outer race lip circle, to guarantee the Stability Analysis of Structures of battery pack; The perforate that is opened in the heat radiation of base plate can make battery pack and space outerpace keep good heat exchange, and the heat that makes battery pack produce can in time distribute.
For self-contained battery better, in the scope of outer race lip, the one side that convexes with the outer race lip of base plate is provided with middle bilge cod.Middle bilge cod can make battery obtain better fixing with the outer race lip together.The quantity of middle bilge cod can be provided with according to actual needs.
Can offer louvre at middle bilge cod, the position corresponding to louvre on the base plate offers through hole.Like this, can obtain better radiating effect.
Can also on the inwall of outer race lip, be provided with and the suitable pit of battery profile.Like this, the contact area between battery and the outer race lip inwall can be bigger, and battery pack has better structural stability.
Vibration absorber can adopt elasticity electric insulation material, and this can make the possibility of battery wearing and tearing reduce.
For improving the intensity of vibration absorber, on the base plate strengthening rib strip can be set.
The outer race lip can adopt continuous structure or intermittent configuration.
The beneficial effects of the utility model are: simple in structure, easy to implement, easy to use; Have good structural stability, sturdy and durable, good heat dissipation effect, fire-retardant, insulation.
[description of drawings]
Below by embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail:
Fig. 1 is the schematic diagram that the multiple batteries connection in series-parallel connects in the battery pack;
Fig. 2 is the schematic perspective view of a kind of execution mode of the utility model vibration absorber;
Fig. 3 is the schematic perspective view at another visual angle of vibration absorber shown in Figure 2;
To be two vibration absorbers shown in Figure 2 be fastened on the battery pack view before the two ends up and down to Fig. 4.
[embodiment]
Fig. 2-Fig. 4 shows a kind of embodiment of the utility model vibration absorber.
As shown in Figure 2, this vibration absorber comprises base plate 1, and base plate 1 offers the perforate 3 of heat radiation; Convex with outer race lip 6 around base plate 1 upper surface, outer race lip 6 is continuous distribution, and the inwall of outer race lip 6 is provided with the pit suitable with the battery profile (Fig. 2 pits is a circular arc); In the scope of outer race lip 6, the upper surface of base plate 1 is provided with middle bilge cod 5, and louvre 2 is offered in the centre of middle bilge cod 5, and the position corresponding to louvre 2 on the base plate 1 offers through hole.Between each circular arc pit and two middle bilge cods 5, and between four adjacent middle bilge cods 5, can hold a battery with respect to the pit opening.
This vibration absorber adopts elasticity electric insulation material.The voltage acquisition holding wire can also outer be drawn in perforate 3 on the base plate 1.
Fig. 3 has disclosed this vibration absorber invisible back side in Fig. 2.As shown in Figure 3, the back side of base plate 1 is provided with the strengthening rib strip 4 that can improve vibration absorber intensity.
When using this vibration absorber, the two ends up and down of each battery that can be in battery pack respectively fasten a vibration absorber respectively, two vibration absorbers are fixed.Fig. 4 shows two vibration absorbers and is fastened on battery pack situation before the two ends about in the of 7.Battery pack 7 adopts 26650 type batteries, and the connected mode between the battery is 4 and 11 strings.Battery is 4 level combinations in parallel earlier, and 11 groups of 4 such combination stacks in parallel constitute 4 and 11 string battery pack 7.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
