And rigid test board 210.The support block 230 is simulation plot, for supporting the rigid test board 210.The rigid test board 210
Upper surface there is the ground of at least two different flatness, when so testing, it is possible to select different ground as landing
Point, reaches the purpose that simulation reality is fallen.Ground described in the present embodiment is by being set not on the rigid test board 210
With flatness surface, for example, various rigid projections are set, such as point is raised or other are raised.The present embodiment preferably rigidly survey
The ground that the upper surface of test plate (panel) 210 has includes ground grading 213, with raised 217 ground 211 of corner angle and with round platform projection
219 ground 215.The rigid test board 210 is connected with the reciprocating air cylinder 220 is acted on the test box by its (reciprocating air cylinder 220)
Pumped in body 20.When the top cover 10 seals fixed with the test casing 20, the reciprocating air cylinder 220 drives this rigidly to survey
Test plate (panel) 210 moves by the steam vent 121 to drive air in the test casing 20 out of forms negative pressure in the test casing 20, should
Rigid test board 210 is arrived at after the support block 230, carries out drop test.
The course of work of many ground condition lithium battery free falling test device of the present embodiment is as follows：First, the grabbing claw 133
Capture lithium battery 30 to be measured；Then, lid 10 is placed in the opening 240 on this, due to Action of Gravity Field, lid 10 and the test on this
Casing 20 reaches the state of pre-fixing；Secondly, first motor 141 control expansion link is above carried, and the upper plate 100 and lower plate 120 are extruded
The sealing ring 110, sealing ring 110 fixes lid 10 and the test sealing of casing 20 on this, and now, reciprocating air cylinder 220 promotes rigidity
Test board 210 is moved, and air is discharged by steam vent 121, air discharge final vacuum bore closure, and the reciprocating air cylinder 220 is back
Motion, the rigid test board 210 is kept in the center, and realizes the test negative pressure of casing 20；Again, original position is returned in rigid test board 210
Afterwards, that is, when arriving in the support block 230, second motor 127 rotation drives screw mandrel 290 to rotate, when grasping mechanism 130 reaches pre-
When determining above the ground, second motor 127 stops the rotation, and the grabbing claw 133 decontrols the lithium battery 30 and carries out free-electron model test；
Subsequently, the reciprocating air cylinder 220 is up moved to transport mesuring battary to grabbing claw and captured again for it, is carried out again freely
Drop test, so drop test is multiple repeatedly, until completing test；Finally, steam vent is opened, and outside air enters test box
Body 20, when inner and outer air pressure is identical, first motor 141, which moves down the lower plate 120, makes sealing ring not compact, opens and is covered on this
10, the lithium battery 30 is taken out, test is completed.
Many ground condition lithium battery free falling test device of the present utility model is in closed during drop test
State, explodes during battery falls, and is that comparison is safe for external staff, furthermore, due to test
During be to be in negative pressure state inside test device, threat of the battery explosion to external staff is just smaller.Meanwhile, negative pressure also can
The resistance that battery falls in sealing space is enough reduced, the effect that simulation is truly fallen is reached.Further, negative pressure can increase in battery
External differential, this pressure difference will than the pressure difference (for an outside standard atmospheric pressure) produced during user use
Greatly, therefore, test condition is more strict compared with truth, preferably ensure that the security of the battery by the test.
Many ground condition lithium battery free falling test device provided by the utility model is described in detail above, this
Apply specific case in text to be set forth principle of the present utility model and embodiment, the explanation of above example is
It is used to help understand core concept of the present utility model；Simultaneously for those of ordinary skill in the art, according to the utility model
Thought, will change in specific embodiments and applications, in summary, this specification content should not be understood
For to limitation of the present utility model.
