Description
Technical field
It the utility model is related to field of batteries, and in particular to a kind of explosion-proof early warning battery.
Background technology
Lithium metal battery can realize quick charge, with as the widely used lithium battery secure replacement product of current institute, but
It is that its security performance is a very important link currently for for lithium metal battery, this is also to restrict lithium metal battery
One key factor of development, when battery can produce gas in use, inside it, inside battery air pressure is caused gradually to increase
Greatly, often there is battery bulging existing, phenomena such as leakage, aluminum plastic film burst, What is more in non-normal use due in battery
Portion's pressure is excessive and causes battery explosion, and the people and thing for making surrounding sustain damage.
Utility model content
The utility model provides a kind of vibration damping, pressure release, the anti-explosion battery of early warning.
To achieve these goals, the utility model adopts the following technical scheme that：The lithium metal battery former material is by shockproof
Pad is fixed in housing, and the housing side is provided with relief hole, and pressure release set is fixed with outside relief hole, and pressure release set inwall side is provided with
The second wafer, and spring is fixed with pressure release set, the opposite side of spring is fixed with explosion-proof plug, the explosion-proof plug and relief hole interference
Relief hole is blocked in cooperation, and explosion-proof plug is provided with the first contact on the outside of relief hole, when spring contraction, the first contact and second
Contact pad.
Further, the second wafer electrically connects with alarm, and alarm electrically connects with dry cell, and dry cell and first touches
Piece electrically connects.
Further, the inner walls are provided with flame-retardant layer.
Further, the crash roll is natural rubber.
Further, the pressure release set is through-hole structure.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model has following excellent
Point：The crash roll can reduce to be shaken caused by the work of lithium metal battery former material, improves its functional reliability, the housing one
The explosion-proof plug set at the relief hole of side can prevent ambient atmos from entering, while when lithium metal battery air pressure inside is excessive,
Explosion-proof plug can be caused to depart from relief hole, reach the purpose of timely pressure release, prevent lithium metal battery from exploding, and let out when explosion-proof plug departs from
When pressing hole, the first fixed contact contacts with the second wafer in pressure release set on explosion-proof plug, connects dry battery power, can make alarm
Device and alarm, reduce the probability that accident occurs.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art：
Fig. 1 is the structural representation of explosion-proof early warning lithium metal battery.
Fig. 2 is Fig. 1 A to enlarged diagram.
Fig. 3 is alert operation schematic diagram.
Embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.
Refering to shown in accompanying drawing 1,2, the lithium metal battery former material 4 is fixed in housing 3 by crash roll 1, can reduce lithium gold
Category battery former material 4 works caused vibrations, improves its functional reliability, the side of housing 3 is provided with relief hole 7, relief hole 7
Outer to be fixed with pressure release set 11, pressure release covers 11 inwall sides and is provided with the second wafer 12, and is fixed with spring 10, spring in pressure release set 11
10 opposite side is fixed with explosion-proof plug 8, and the explosion-proof plug 8 and relief hole 7 are interference fitted pressure release using the elastic force of spring 10
Hole 7 is blocked, and when lithium metal battery internal pressure is more than 10 elastic force of spring, explosion-proof plug 8 departs from relief hole 7, and explosion-proof plug 8 is in letting out
The outside of pressure hole 7 is provided with the first contact 9, and when spring contraction, the first contact 9 contacts with the second wafer 12.
Refering to shown in accompanying drawing 3, the second wafer 12 is electrically connected with alarm 13, and alarm 13 is connected with dry cell electricity 14, is done
Battery 14 electrically connects with the first contact 9, when the first contact 9 contacts with the second wafer 12, that is, connects the power supply of dry cell 14, alarm
The automatic alarm of device 13, this is simple and practical, while realizing warning function, will can substantially reduce the probability of accident generation.
Specific embodiment of the present utility model is above are only, but design concept of the present utility model is not limited thereto,
All changes for carrying out unsubstantiality to the utility model using this design, all should belong to the row for invading scope of protection of the utility model
For.
