Internal pressure gradually rises afterwards, it is possible to cause the apparatus structure of fixed module damaged, make whole system cisco unity malfunction.It is existing
Pressure sensor can only measure the pressure of some position, be unable to simulated battery in the state of practical application；Existing pressure detecting
Device cannot record change value of pressure of the battery under life-cycle cycle period in real time.
Utility model content
The utility model is in order to overcome the shortcomings in the prior art, to provide a kind of lithium ion battery life cycle management pressure
Test fixture, the pressure change of real-time monitoring sample, week detection battery life-cycle may be implemented in connection data collector
The variation of phase pressure provides great data to the structure design of battery modules and system and supports.
The utility model to achieve the above object, is achieved through the following technical solutions, a kind of week lithium ion battery life-cycle
The test fixture of phase pressure, it is characterized in that: including bottom plate, sliding clamp, sensor fixation plate, sensor, limited post, support plate
With deceleration elevating drive mechanism, limited post, limited post and sliding clamp and sensor fixation plate are symmetrically connected on the bottom plate
It is slidably connected, limits the affixed support plate in top end, be connected with deceleration elevating drive mechanism, deceleration elevating drive mechanism in support plate
Front end and sensor fixation plate upper surface are affixed, and the lower surface of the sensor fixation plate is connected with sensor.
Limit slip ring is respectively arranged on the sliding clamp and sensor fixation plate.
The sliding clamp is equipped with the circular hole that can pass through sensor.
The limited post quantity is 4-8.
The deceleration elevating drive mechanism uses hand-cranked spiral transmission mechanism.
The bottom plate, sliding clamp, sensor fixation plate and support plate quadrangle are equipped with chamfering.
The utility model has the advantages that compared with prior art, the utility model can acquire the sensor on test fixture with data

Function is accurately controlled the height that adjustment is promoted or promoted by certain procedures, can directly be driven with motor or other power,
It can also be manual.
The course of work
Limited post 2 is fixed on first and is held successfully on the bottom plate 1 of symmetrical holes in advance, on sliding clamp 3 and sensor fixation plate 4
Installation limit slip ring 8 respectively, limit slip ring play damping position-limiting action.Sliding clamp 3 and sensor fixation plate set are attached to limit
On the column 2 of position, by support plate 6 by holding symmetrical hole successfully in advance and be fixed on limited post 2, then by deceleration elevating drive mechanism 7
It is fixed in support plate 6, finally fixes 7 front end of deceleration elevating drive mechanism and 4 upper surface of sensor fixation plate.
Sensor is first connect to display pressure reading with data collector when in use, battery sample is placed on bottom plate 1
Between sliding clamp 3, manually adjusting deceleration elevating drive mechanism 7 touches sensor with battery sample, i.e., to battery sample
One pretightning force, keeps this position motionless, then carries out charge and discharge to battery sample, and collect pressure value by collector,
Test the real-time pressure value variation of sample.
It is above-mentioned referring to embodiment to the detailed description of the one kind, be illustrative without being restrictive, can be according to being limited
Determine range and enumerate several embodiments, therefore all changes and modifications without departing from the scope of the present general inventive concept, this should be belonged to
Within the protection scope of utility model.
