Embodiment:
A kind of Novel electric core fire prevention cylinder, as shown in figure 1, figure 2, figure 3, figure 4 and figure 5, including fire proof construction and diaphragm structure, Fire proof construction and diaphragm structure use the fire-retardant material of high-temperature insulation;Fire proof construction include fire prevention cylinder 1, fire prevention cylinder 1 by It the assembly cylinder 11 that is in contact with battery core surface and is formed with the discontiguous heat-insulated cylinder 12 in battery core surface, the width of heat-insulated cylinder 12 Degree is greater than the width of assembly cylinder 11;Assembly cylinder 11 is connected with heat-insulated cylinder 12, assemble cylinder 11 and heat-insulated cylinder 12 it Between use chamfering or round-corner transition;The depth for assembling cylinder 11 is less than the depth of heat-insulated cylinder 12;Assembling cylinder 11 is cylinder Shape slot;The cross section of heat-insulated cylinder 12 is round or polygon;The end for assembling cylinder 11, which is equipped with, carries out axial direction and diameter to battery core The nickel sheet fitting groove 13 of assembly located space is provided to position constraint, and to nickel sheet;Diaphragm structure include and assembly 11 end of cylinder The connecting plate ontology 2 that portion is connected, connecting plate ontology 2 are equipped with the dashpot 21 to match with assembly cylinder 11;Dashpot 21 Edge extended outward to form isolation ring 22;The outer surface of the isolation ring 22 is matched with the inner surface of assembly cylinder 11; It is equipped with several relief holes 23 in dashpot 21, is used for pressure release.
In the present embodiment, assembly cylinder 11 is equipped with to lock screw hole 14, stud 15, button bit 16, side screw hole 17.To lock spiral shell Wire hole 14 makes may be used also to solid battery core, stud 15 and button bit 16 is locked for assembling fixed BMS by screw between fire prevention cylinder To allow the mould group organized to be securedly mounted in equipment.
In the present embodiment, connecting plate ontology 2 is equipped with the mounting hole 24 being connected with assembly cylinder 11;Outside dashpot 21 Side is equipped with reinforcing rib 25, increases stability.
In the present embodiment, as shown in Figure 1, Figure 6, Figure 7, fire prevention cylinder 1 is by the assembly cylinder 11 that is in contact with battery core surface Formed with the discontiguous heat-insulated cylinder 12 in battery core surface, heat-insulated 12 depth of cylinder is deeper, can wrap up battery core, but with battery core table Face is not directly contacted with, and there are certain spaces for storing air, and heat-insulated 12 cross section of cylinder can be designed as circle, can also be with It is designed as polygonal in form according to the actual situation, uses chamfering or round-corner transition between heat-insulated cylinder 12 and assembly cylinder 11, it can There is guiding performance when allowing battery core to be packed into, is easier to assemble;An economize on electricity core occur it is abnormal it is hot walk cruelly when, failure battery core can issue largely Heat, this heat first heats the air of thermal insulation areas 3 at this time, and since air thermal conductivity itself is poor, high fever passes through Fire prevention cylinder 1 is reached after the air transmitted of thermal insulation areas 3, prevents fires cylinder 1 when delivering heat to the thermal insulation areas 3 of adjacent battery core, itself Absorb partial heat and be conducted to diaphragm structure, and adjacent battery core is after itself 3 air barrier of thermal insulation areas, temperature again under Drop, thus the high fever for issuing abnormal battery core, after 3 grades of transmitting, the heat at adjacent battery core is reduced to 130 degree of safety temperature Degree avoids prolonging and burns phenomenon appearance hereinafter, to guarantee that adjacent battery core will not be damaged.
In the present embodiment, dashpot 21 effect be battery core heat cruelly walk when, battery core anode by the excessive rupture of pressure, battery core When internal high temperature high pressure matter sprays, a barrier and buffer function are played, avoids this high temperature substrate is upright from connecing ejection and be diffused in battery Inside, causing adjacent battery core temperature is more than 130 degree of electric core membrane damage temperature, so that adjacent battery core is damaged chain heat and walks cruelly;In addition, Design has the rib ring being higher by form isolation ring 22, the internal diameter phase of diameter and nickel sheet fitting groove 13 on dashpot 21 Together, it can be inserted in nickel sheet fitting groove 13 when assembly, by the space partition at every battery core nickel sheet, avoid high temperature and pressure substance slow Jet-bedding 21 is transmitted to from adjacent battery core after being obstructed from the gap of nickel sheet fitting groove 13, is damaged chain heat and is walked cruelly;It is buffering Slot 21 offers several relief holes 23, for discharging the pressure in dashpot 21, avoids hypertonia that mould group is caused to explode.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other related technical areas are also included in the patent protection scope of the utility model.
