Bottom is installed with infrared electro inductor, and the bottom extended line of the infrared electro inductor intersects with infrared reflective plate, described
Infrared electro inductor is electrically connected with being fixedly arranged on the induction alarm lamp of top plate.
Further scheme, the both sides of the strap and sideboard are fixedly connected by screw rod with support plate respectively,
Spring is arranged with screw rod between sideboard and support plate；Gap between the strap and sideboard is just
The good thickness with tested lithium battery is adapted.
The input terminal of further scheme, the output terminal of the pressure sensor and controller connects, the controller it is defeated
Outlet is connected with the charge power supply of tested lithium battery.
The present apparatus when in use, long ear-pole is first welded on tested lithium battery, tested lithium battery then is placed in fixation
Clamped between clamping plate and sideboard, long ear-pole is connected by power cord with external charging power supply circulates tested lithium battery
Charge and discharge is electrically operated, and pressure value is transmitted in pressure sensor collection activity baffle and the effect of tested lithium battery, is remembered in real time by controller
The pressure value and variation tendency during lithium battery cycle charging are recorded, and sets a upper pressure limit value.Then pressure sensor can
The aerogenesis situation of the tested lithium battery of monitoring in real time, when battery volume is expanded into upper limit value, can promote and move and hinder outside sideboard
Hinder the reflection of the infrared ray of infrared photoelectric sensor transmitting, when it does not receive the reflection of infrared ray, induction alarm lantern festival hair
Go out alarm signal；When pressure value, which reaches, sets upper pressure limit value in controller, controller can then stop the charge and discharge to lithium battery
Electric behavior, ensure that the security of lithium battery.
The long ear-pole welded in the present apparatus has certain standard, its material and uniform specification, excludes lug to testing process
Influence.
So the helpful of the utility model is：By the shape of the situation of the aerogenesis of tested lithium battery and charge and discharge cycles
Condition connects, and the data gathered by pressure sensor, analyze each stage aerogenesis situation in charge and discharge cycles, with reference to following
The data of ring capacity can help the cycle performance of analysis product.
The utility model biggest advantage be in real time monitoring battery aerogenesis situation, when battery volume be expanded into it is certain
The limit, stops the discharge and recharge behavior to lithium battery immediately.

Embodiment
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is attached drawing needed in technology description to be briefly described.
As shown in Figure 1, a kind of be used to detect lithium ion battery circulation aerogenesis expansion alarm protecting apparatus, including by support plate
11st, the half frame shape supporting rack that bottom plate 14 and top plate 10 are formed by connecting, is vertically installed with strap 4 on the bottom plate 14, is located at
Sideboard 5 and pressure sensor 9 are equipped with bottom plate 14 between strap 4 and support plate 11 successively, by sideboard 5,
Infrared reflective plate 7 is equipped with the bottom plate that pressure sensor 9 and support plate 11 enclose；The both ends difference of the pressure sensor 9
Contacted with sideboard 5, support plate 11；The bottom of the top plate 10 is installed with infrared electro inductor 6, the infrared light inductance
The bottom extended line of device 6 is answered to intersect with infrared reflective plate 7, the infrared electro inductor 6 and the sensing report for being fixedly arranged on top plate 10
Warning lamp 8 is electrically connected.
Further scheme, the both sides of the strap 4 and sideboard 5 are fixed by screw rod 12 and support plate 11 respectively
Connect, spring 13 is arranged with the screw rod 12 between sideboard 5 and support plate 11；The strap 4 and active catch
Thickness of the gap just with tested lithium battery 1 between plate 5 is adapted.Sideboard 5 is set on screw rod 12 and can move left and right,
And spring 13 does not have active force to it.
The input terminal of further scheme, the output terminal of the pressure sensor 9 and controller connects, the controller it is defeated
Outlet is connected with the charge power supply of tested lithium battery 1.
The present apparatus welds long ear-pole 2 on tested lithium battery 1 when in use, first, is then placed in tested lithium battery 1 solid
It is clamped between clamp plate 4 and sideboard 5, long ear-pole 2 is connected by power cord 3 with external charging power supply to tested lithium electricity
Pond carries out circulation and is filled with electrically operated, the effect transmission pressure value of 9 collection activity baffle 5 of pressure sensor and tested lithium battery 1, by
Controller records the pressure value and variation tendency during lithium battery cycle charging in real time, and sets a upper pressure limit value.Together
When open infrared electro inductor 6, the infrared ray that when its work launches is after the transmitting of reflecting plate 7 and is received, and feels at this time
Alarm lamp 8 is answered to be closed.
When lithium battery constantly carries out charge and discharge cycles, it can produce and a degree of expansion occurs, and then promotion activity
Baffle 5 to 9 direction of pressure sensor move, due to the pressure sensor 9 both ends respectively with sideboard 5, support plate 11
Contact, so exerting a force to pressure sensor 9；When degrees of expansion is bigger, the output pressure signal value of pressure sensor is bigger.
When charging and discharging lithium battery is recycled to certain all number, when its volumetric expansion is to upper limit value, shifting outside sideboard 5 can be promoted
And the reflection of the infrared ray of the transmitting of infrared photoelectric sensor 6 is hindered, and when it does not receive the reflection of infrared ray, induction alarm lamp
8 can send alarm signal；When pressure value, which reaches, sets upper pressure limit value in controller, controller can then stop to tested lithium electricity
The discharge and recharge behavior in pond 1, ensure that the security of lithium battery.
