Abstract
Disclosed is a device for testing the lithium ion battery safety performance, comprising a weight, a pedestal, an explosion-proof case, a sliding cylinder, and a piston rod, wherein the explosion-proof case is fixed upon the pedestal; the sliding cylinder is vertically arranged upon the top of the explosion-proof case; and the weight can drop along the sliding cylinder. With the above technical scheme, a heavy object is placed at a certain height and freely falls down via the telescoping motion of the piston rod in the cylinder. The heavy object falls upon the to-be-detected sample in the explosion-proof case, thereby determining the capability of the lithium ion battery product for standing the strike of a heavy object. The device can precisely test the safety performance of the lithium ion battery product of standing the strike of a heavy object, with a simple structure, safe and convenient operation, and low cost.
Description
Technical field
The utility model relates to the device that a kind of lithium ion battery carries out the weight impact test, evaluation lithium ion battery product safety performance.
Background technology
Because the continuous expansion in electric tool market, countries in the world all replace nickel-cadmium battery being devoted to develop the environment-friendly type lithium ion battery that electric tool uses.Lithium ion battery is in fast development, and its security performance also receives much concern.At present, lithium ion battery all adopts protection system that battery is carried out safeguard protection in use, but protection system can not reach 100% reliability when reality is used.This just requires lithium ion battery must have the ability to bear of good abuse and fortuitous event, and the relevant safety test that must pass through just can be guaranteed the security of using.
The utility model content
The utility model technical matters to be solved provides a kind of lithium ion battery security can proving installation, can the objective evaluation lithium ion battery when receiving unexpected weight bump, whether have potential safety hazards such as on fire or blast.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: lithium ion battery security ability proving installation; Comprise weight, base, explosion-proof tank, slide cartridge, piston rod; Said explosion-proof tank is fixed on the said base, and said slide cartridge vertically is located at the top of said explosion-proof tank, and said weight can fall along said slide cartridge.
As preferably, laterally be provided with an opening on the said slide cartridge, be provided with piston rod in the said opening, said piston rod flexibly connects through this opening and said slide cartridge.
As preferably, said piston rod is by air cylinder driven,
As preferably, said cylinder connects controller through electric wire.
As preferably, said cylinder is located on the bracing frame, and support frame as described above is connected on the support bar through height adjuster.
As preferably, be provided with anchor clamps in the said explosion-proof tank, so that fixing mesuring battary sample.
The utility model is placed on weight on the certain altitude owing to adopted technique scheme, through stretching of piston rod in the cylinder; Weight is freely fallen on certain altitude, fall on the explosion-proof casing testing sample, thereby judge that the lithium ion battery product bears the weight jolt capacity; Can accurately test the security performance that the lithium ion battery product bears the weight bump; Apparatus structure is simple, easy-to-operate, and cost is lower.
