Abstract
The utility model discloses a device used for air-tightness testing of a lithium-Ion cell. The device is characterized by mainly including a base (1), a testing cabin (3) fixed on the base (1) and provided with a cell entrance (2), a hydraulic pump (4) fixed on the base (1), a push rod connected fixedly with the hydraulic pump (4) and a cabin cover (5) which matches the cell entrance (2). An air pump (6) is fixed on the outer wall of the testing cabin (3) and the air pump (6) communicates with the internal part of the testing cabin (3) through a pipe. At the same time, self-adhesive sealing rings (7) are arranged on both of the end face of the cell entrance (2) of the testing cabin (3) and the end face of the cabin cover (5). The self-adhesive sealing rings are arranged on the contact end faces of the cabin cover and the testing cabin so that when the cabin cover and the testing cabin are closely pressed together, the self-adhesive sealing rings can be bonded together well and thus it is ensured that no air-pressure leakage exists in the testing cabin so that the accuracy of testing data is ensured.
Description
Technical field
The utility model relates to a kind of lithium ion battery device for testing, specifically refers to a kind of lithium ion battery airtightness device for testing.
Background technology
The quality of vehicle-mounted great-capacity power battery performance affects the overall performance of electric automobile, if the sealing of high capacity lithium ion battery is poor, will affect serviceable life and the security of lithium ion battery, therefore, develop a kind of device that can fast detecting lithium ion battery airtightness and there is great practice significance for the life-span and the security that improve lithium ion battery.Although have on the market some can detect the device of lithium ion battery airtightness at present, but these apparatus cost costs are comparatively expensive, and the sealing property of these proving installations itself neither be very desirable, so its data that test out and the certain error of physical presence, can not extensively promote and use.
Utility model content
The purpose of this utility model is to overcome at present for testing existing expensive, the sealing of device of lithium ion battery airtightness own not strong, and the defect of test data and the larger error of real data existence, provide a kind of simple in structure, can significantly dwindle the lithium ion battery airtightness device for testing of error.
To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of lithium ion battery airtightness device for testing, mainly by pedestal, be fixed on pedestal and there is the test storehouse of battery import, be fixed on the hydraulic pump on pedestal, and be fixedly linked and form with the Cang Gai that battery import matches with the push rod of hydraulic pump; On the outer wall in test storehouse, be fixed with inflator pump, and this inflator pump is connected with the inside in test storehouse by pipeline; Meanwhile, on the end face of battery import of testing storehouse and on the end face of Cang Gai, be equipped with autohension O-ring seal.
In order to realize preferably the utility model, described test storehouse is integrated injection molded, and is also provided with tensimeter on inflator pump.
Meanwhile, on test storehouse, be also provided with elbow folder, in storehouse, cover and be provided with the buckle matching with this elbow folder.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model one-piece construction is very simple, uses and makes very convenient.
(2) the utility model adopts hydraulic pump to be used as the thrust of Cang Gai, therefore can guarantee that Cang Gai and test storehouse can tightly combine.
(3) the utility model is provided with autohension O-ring seal at Cang Gai and contacting of test storehouse on end face, therefore when Cang Gai and test storehouse compression, this autohension O-ring seal just can well be bonded together, and guarantees to test in storehouse, not have any air pressure and reveal, thereby guarantees the accuracy of test data.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Wherein, the Reference numeral title in accompanying drawing is respectively:
1-pedestal, the import of 2-battery, 3-test storehouse, 4-hydraulic pump, 5-Cang Gai, 6-inflator pump, 7-autohension O-ring seal, 8-tensimeter, 9-elbow folder, 10-buckle.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, pedestal 1 of the present utility model is prepared from by metal material, is fixed with test storehouse 3 and hydraulic pump 4 on this pedestal 1.Hydraulic pump 4 maintains 10～20cm spacing apart from test storehouses 3, and structure and the size of storehouse lid 5 match with test storehouse 3, and this storehouse lid 5 is connected to a fixed with the push rod of hydraulic pump 4, to guarantee that storehouse covers 5 promotions that can be subject to hydraulic pump 4.
A side in test storehouse 3 is provided with the battery import 2 of putting into for lithium ion battery, on the outer wall in test storehouse 3, is fixed with inflator pump 6.This inflator pump 6 is connected with the inside in test storehouse 3 by pipeline, to guarantee that the test gas that inflator pump 6 is pumped can enter through pipeline the inside in test storehouse 3.
In order to ensure security performance, this test storehouse 3 and storehouse lid 5 all will be shaped by metal material integrated injection molding, meanwhile, also will be provided with the tensimeter 8 that embodies test storehouse 3 air pressure inside value sizes on inflator pump 6.
Because the quality of sealing between storehouse lid 5 and test storehouse 3 has directly determined mistake extent, thus the utility model on the end face of the battery import 2 in test storehouse 3 and storehouse cover on 5 end face and be equipped with autohension O-ring seal 7.This autohension O-ring seal 7 is soft encapsulant, when storehouse lid 5 under the thrust of hydraulic pump 4 when be tightly combined in test storehouse 3, the autohension O-ring seal 7 that is positioned at the autohension O-ring seal 7 on storehouse lid 5 and is positioned on test storehouse 3 just can tightly be bonded together, and forms an integral body; When storehouse lid 5 is separated with test storehouse 3, these two autohension O-ring seals 7 are separable opening just.
In order further to guarantee safety, therefore on test storehouse 3, be also provided with elbow folder 9, on storehouse lid 5, be provided with and these elbow folder 9 buckles that match 10.When test, directly elbow folder 9 is fastened on buckle 10.
As mentioned above, just can realize preferably the utility model.
