Abstract
Blast resistant construction of lithium ion battery block, it includes steel cap, thermistor, explosion -proof valve, metallic interconnect piece and rubber ring cover, steel cap, thermistor, explosion -proof valve and metallic interconnect piece top -down closed assembly, the rubber ring ways is located outside the outer fringe of steel cap, thermistor, explosion -proof valve and metallic interconnect piece, the bottom surface of this explosion -proof valve is equipped with explosion -proof nick. The utility model discloses a this explosion -proof valve position is between thermistor and metallic interconnect piece, and explosion -proof nick is located the bottom surface of explosion -proof valve, so, even there is battery liquid to remain the top surface at explosion -proof valve, battery liquid can not touch explosion -proof nick yet, and the misconvergence collection can avoid battery liquid to perforate in explosion -proof nick, and the security is higher.
Description
Technical field
The utility model relates to a kind of blast resistance construction of lithium ion battery cover.
Background technology
For improving security performance, lithium ion battery cover is generally provided with explosion-proof valve, and the end face of explosion-proof valve is provided with explosion-proof indentation, and after battery liquid-filling, residual battery fluid is on the indentation of explosion-proof valve sometimes, and the time one is of a specified duration, there will be battery fluid perforated phenomenon, explosion-proof valve was lost efficacy.
Utility model content
For the deficiencies in the prior art, the utility model is intended to the blast resistance construction providing a kind of lithium ion battery cover solved the problems of the technologies described above.
For achieving the above object, the utility model adopts following technical scheme:
A blast resistance construction for lithium ion battery cover, it comprises steel cap, thermistor, explosion-proof valve, metal connecting sheet and cushion rubber cover;
Steel cap, thermistor, explosion-proof valve and metal connecting sheet closed assembly from top to bottom, cushion rubber cover is sheathed on outside the outer rim of steel cap, thermistor, explosion-proof valve and metal connecting sheet; The bottom surface of this explosion-proof valve is provided with explosion-proof indentation.
Preferably, explosion-proof valve comprises depressed part and plane ring portion, and plane ring portion is formed from the upper limb horizontal expansion of depressed part, and this explosion-proof indentation is located at the bottom surface of plane ring portion.
Preferably, this explosion-proof indentation in the form of a ring.
Preferably, this metal connecting sheet is aluminum brace.
The beneficial effects of the utility model are at least as follows:
This explosion-proof valve of the present utility model is between thermistor and metal connecting sheet, explosion-proof indentation is positioned at the bottom surface of explosion-proof valve, so, even if there is battery fluid to remain in the end face of explosion-proof valve, battery fluid also can not touch explosion-proof indentation, can not be gathered in explosion-proof indentation, battery fluid can be avoided to bore a hole, and fail safe is higher.
Accompanying drawing explanation
Fig. 1 is the generalized section of the better embodiment of the blast resistance construction of the utility model lithium ion battery cover.
Fig. 2 is the generalized section of the explosion-proof valve of the blast resistance construction of the lithium ion battery cover of Fig. 1.
Fig. 3 is the elevational schematic view of the explosion-proof valve of the blast resistance construction of the lithium ion battery cover of Fig. 1.
Fig. 4 is the schematic top plan view of the steel cap of the blast resistance construction of the lithium ion battery cover of Fig. 1.
Fig. 5 is the schematic top plan view of the metal connecting sheet of the blast resistance construction of the lithium ion battery cover of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
Refer to Fig. 1 to Fig. 5, the utility model relates to a kind of blast resistance construction of lithium ion battery cover, and its better embodiment comprises steel cap 10, thermistor 20, explosion-proof valve 30, metal connecting sheet 40 and cushion rubber cover 50.
Steel cap 10, thermistor 20, explosion-proof valve 30 and metal connecting sheet 40 closed assembly from top to bottom, cushion rubber cover 50 is sheathed on outside the outer rim of steel cap 10, thermistor 20, explosion-proof valve 30 and metal connecting sheet 40; The bottom surface of this explosion-proof valve 30 is provided with explosion-proof indentation 15.
This explosion-proof valve 30 of the present utility model is between thermistor 20 and metal connecting sheet 40, explosion-proof indentation 15 is positioned at the bottom surface of explosion-proof valve 30, so, even if there is battery fluid to remain in the end face of explosion-proof valve 30, battery fluid also can not touch explosion-proof indentation 15, can not be gathered in explosion-proof indentation 15, battery fluid can be avoided to bore a hole, and fail safe is higher.
Preferably, explosion-proof valve 30 comprises depressed part 16 and plane ring portion 17, and plane ring portion 17 is formed from the upper limb horizontal expansion of depressed part 16, and this explosion-proof indentation 15 is located at the bottom surface of plane ring portion 17.So, residual battery fluid will be gathered in depressed part 16, thus isolate with explosion-proof indentation 15.
Preferably, this explosion-proof indentation 15 in the form of a ring.
Preferably, this metal connecting sheet 40 is aluminum brace.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection range of the utility model claim.
