Description
Technical field
The utility model relates to solid state cell technology fields, and in particular to a kind of solid state battery protective device.
Background technique
With the development of solid state battery, safety is also more and more paid attention to.The insurance of current solid state battery
Wire feed mechanism and thermistor mechanism are not avoided that the positive and negative anodes due to battery issue heat decomposition in hyperthermia and superheating and cause more but
More pyrolysis heat release problems.It will cause thermal runaway in this way and cause more serious unsafe condition.Therefore, in order to improve solid-state
The safety of battery, it is desirable to provide a kind of from different protection mechanism at present.
Summary of the invention
The problem of purpose of the utility model is to solve current solid state battery safeties provides a kind of solid state battery guarantor
Protection unit.
In order to reach above-mentioned purpose of utility model, the utility model uses following technical scheme:
A kind of solid state battery protective device, the main body including plate-like set that there are four terminals, four wiring end ring in main body
Around setting, and external insulation block is equipped between two neighboring terminals, external insulation block, which insulate two neighboring terminals, to be connected；
The alloy body of low melting point, alloy body four are equipped at the center of four terminals and external insulation block in forming region
Set in week there are four interior insulation block, form the independent channel for respectively leading to four direction by alloy body between interior insulation block, it is outer absolutely
The part of the whole of edge block and two neighboring terminals is exposed in channel, and two opposite terminals are connected.
Preferably, further include cover board, after the cover board and body cover conjunction, four channels are formed into sealing spaces.
Preferably, the alloy is cylinder.
Preferably, the terminals and external insulation block form circular region.
Preferably, the interior insulation block is sector, and the edge of interior insulation block is connect with terminals.
Preferably, alloy body has plummer.
Preferably, in main body in being equipped with safety groove in each channel, safety groove be opened in terminals and it is outer absolutely
The junction of edge block.
Preferably, the channel gradually tilts down setting by alloy body around.
Compared with prior art, beneficial effect is the utility model:
The terminals connection of positive and negative anodes can be represented in the higher Shi Jiang of battery temperature thus after by the positive and negative anodes connection of battery
By energy quick release, the thermal decomposition of battery at high temperature is avoided, even if after battery temperature reduction, due to the alloy after fusing
Body forms new shape, is also not easy to restore again, and thus the positive and negative anodes of battery can be connected always, avoid problem continue plus
It is deep.

Specific embodiment
Explanation is further described to the technical solution of the utility model below by specific embodiment.
Embodiment:
A kind of solid state battery protective device, as shown in Figure 1, 2, 3, the main body 1 including plate-like set that there are four connect in main body 1
Line end 2, four terminals 2 are equipped with external insulation block 3 around setting between two neighboring terminals 2, external insulation block 3 will be adjacent
Two insulation connections of terminals 2；Two opposite terminals 2 are connected, that is to say, that opposite terminals form identical battery
Positive or negative pole.
The terminals 2 form circular region with external insulation block 3, and surround in four terminals 2 and external insulation block 3
Center in forming region is equipped with the alloy body 4 of low melting point, and alloy body 4 is surrounded by four interior insulation blocks 5,5 phase of interior insulation block
It is mutually independently arranged, and forms the independent channel 6 for respectively leading to four direction by alloy body 4 between each interior insulation block 5,
The connection of independent 6 one end of channel (i.e. inner end) is at alloy body 4, the other end (i.e. outer end) connection be terminals 2 and it is outer absolutely
Edge block 3, that is to say, that the part of the whole of external insulation block 3 and two neighboring terminals 2 is exposed in channel 6.In this way, when closing
When golden 4 fusing higher due to temperature of body, so that it may flow to two terminals 2, before, two adjacent terminals along channel
2 do not turn on, and after the alloy that fusing has reaches, two adjacent terminals 2 are turned on, thus by the positive and negative of battery
Pole forms short circuit, to protect battery-heating to cause danger.
In the apparatus, further include cover board 7, after the cover board 7 and the lid conjunction of main body 1, four channels 6 formed into sealing spaces,
Alloy after melting in this way can flow in the enclosure space, avoid the alloy of battery caused after fusing when being inverted
It cannot flow in time at terminals 2 and external insulation block 3.
Specifically, the interior insulation block 5 is sector, the edge of interior insulation block 5 is connect with terminals 2.Fan-shaped structure, can
It causes to stop to avoid to the alloy after fusing, reduces the resistance that alloy flows to surrounding, and by the channel 6 by alloy body 4
Place gradually tilts down setting around, also for the flowing for accelerating alloy after melting, meanwhile, it has and holds in alloy body 4
Microscope carrier 8, also for improve alloy body 4 at and surrounding difference in height, accelerate flowing speed.In addition, on the body 1 in each
Safety groove 9 is equipped in channel 6, safety groove 9 is opened in the junction of terminals 2 and external insulation block 3, and safety groove 9 is to incite somebody to action
Alloy after fusing is stored in the slot, can be prevented when without departing from unsafe condition, alloy, which leaves, causes security mechanism to fail.
Further, 1-2mm is set at a distance from terminals 2 by the edge of alloy body 4, it thus can be safe ahead of time
The opportunity of mechanism starting can take safety measures to the battery overheat of generation within the more reasonable time.
