Specific embodiment
Explanation is further explained to technical solutions of the utility model with reference to the accompanying drawing.
Attached drawing 1,2 is compareed, a kind of Battery case of monitoring lithium ion battery expansion bulge, 3 one end of cabinet is hinged with case lid
1, the both ends of the cabinet 3 difference threaded connection bolt 1 and bolt 2 11, the bolt 1 and the bolt 2 11 it is another
One end has been respectively articulated with fixed plate 1 and fixed plate 28, and the cabinet 3 is internally provided with partition 2, the two sides of the partition 2
It is embedded with one group of strain pressure transducer 5 and controller 9, each strain pressure sensor 5 and the controller 9 respectively
Signal output line external power supply is connected to by outlet hole 6, the outlet hole 6 and buzzer 7 are arranged before the cabinet 3
Portion.
Attached drawing 3 is compareed, is provided with terminated line slot 7a in the partition 2 and the cabinet 3, convenient for placing signal output
The length of line, the fixed plate 1 and the fixed plate 28 and the width inside the cabinet 3 coincide, convenient for described in limitation
The direction of motion of fixed plate 1 and the fixed plate 28.
Attached drawing 4 is compareed, one group of gas vent 10 is provided on the case lid 1, convenient for the discharge of pernicious gas, avoids exploding.
Attached drawing 5 is compareed, the strain pressure transducer 5 is made of resistance strain gage and elastic sensing element, when
Elastic sensing element is under pressure when acting on, and will generate strain, and the resistance strain gage for being pasted onto surface can also generate strain, performance
The change of resistance value is shown as after the 5 core element foil gauge of strain pressure transducer generates strain for the variation of resistance value
Change, the resistance value of metallic conductor can be represented by the formula:
