Description
Technical field
The utility model relates to a kind of stationary fixture, more specifically to a kind of lithium-ion-power cell packet vibration test
With fixture, belong to the vibration test technical field of new-energy automobile lithium ion battery packet.
Background technique
Lithium ion battery technology has been widely used in Vehicular dynamic battery field, each due to needing to face in vehicle travel process
Kind road conditions, the vibration of battery caused by road roughness motivates are its important originals for structural fatigue destruction or even global failure occur
Cause, so needing to assess influence of the vibration to battery pack structure and performance by vibration test.
Currently, the fixture for lithium-ion-power cell packet vibration test is heavy, experimental ability is influenced, bad installation, and
Poor universality.
Summary of the invention
The purpose of this utility model is that heavy, the bad peace for existing lithium-ion-power cell packet vibration test fixture
The problems such as dress, poor universality, provide a kind of lithium-ion-power cell packet clamp for vibration test.
To achieve the above object, the technical solution of the utility model is: a kind of lithium-ion-power cell packet vibration examination
It tests with fixture, the rectangle bottom plate including being fixed on shake table, according to the fixation on vibration table on the rectangle bottom plate
Screwhole position is correspondingly arranged on matched threaded hole, and rectangle bottom plate quadrangle is respectively arranged with support base, and rectangle bottom plate is ipsilateral
Support base between connected by loading plate, be provided with arcuate socket on the loading plate.
The distance between the rectangle bottom plate and loading plate are 15~17cm.
The support base using reinforcing design, and support base pass through it is solid respectively with 10.9 grades or more of high-strength bolt
It is scheduled on support base and loading plate.
Compared with prior art, the beneficial effects of the utility model are:
1, this fixture can be fixed well on a vibration table by battery pack, and can simulate it onboard in bracket
State carries out vibration test；And the fixture can be extended for various sizes of battery pack, have comparable versatility.
2, structure is simple, using light-weight design, without redundancy structure and component, makes and installs extremely convenient, be conducive to
Test is carried out and is gone on smoothly.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is the fixed battery pack schematic diagram of the utility model
In figure: rectangle bottom plate 1, threaded hole 2, support base 3, fixing screwed hole 4, loading plate 5, arcuate socket 6, battery pack 7,
Battery pack fixing bolt 8.
Specific embodiment
The utility model is described in further detail below in conjunction with Detailed description of the invention and specific embodiment.
Referring to Fig. 1 to Fig. 2, a kind of lithium-ion-power cell packet clamp for vibration test can be applied to Vehicular dynamic battery
The vibration test of packet, such as the power battery pack anti-vibration performance evaluation test of pure electric vehicle；It can be carried out for battery pack 7
It is good fixed, it simulates the state that it is onboard installed and completes vibration test.This fixture includes the rectangle bottom for being fixed on shake table
Plate 1 is correspondingly arranged on matched threaded hole 2 according to the fixing threaded hole position on vibration table on the rectangle bottom plate 1；Spiral shell
Pit 2 is usually 12, for being fixedly secured rectangle bottom plate 1 in vibration table surface.1 four jiaos of rectangle bottom plate set respectively
It is equipped with cuboid-type support base 3, is used to support 7 battery pack, 7 weight；Pass through carrying between the ipsilateral support base 3 of rectangle bottom plate 1
Plate 5 connects.Arcuate socket 6 is provided on the loading plate 5, loading plate 5 is used to fix battery pack 7；By arcuate socket 6 using electricity
Battery pack 7 is fixed on support base 3 by pond packet fixing bolt 8, and 6 length of arcuate socket can fix different length by design
Battery pack 7.
Referring to Fig. 1 to Fig. 2, certain distance is had in vain between rectangle bottom plate 1 and loading plate 5, the rectangle bottom plate 1 and carrying
The distance between plate 5 is 15~17cm；Therefore Road spectrum vibration examination can be carried out with state of the simulated battery packet 7 on bracket
It tests；And the distance of the design can also avoid battery pack 7 in vibration test from causing deformation to collide the impact force of loading plate 5
Bottom plate has and accommodates the space that loading plate 5 deforms, and influences test and is normally carried out or causes battery pack 7 to damage.
Referring to Fig. 1, further, the support base 3 using reinforcing design, and support base 3 by with 10.9 grades and with
On high-strength bolt be separately fixed on support base 3 and loading plate 5；I.e. force part uses high-strength material, is able to bear
To the impact force of this fixture during vibration test.Specifically, loading plate 5 is by fixing screwed hole 4 using high-strength bolt
It is secured transverse on support base 3.
Referring to Fig. 1 to Fig. 2, this fixture is used for the vibration test of new-energy automobile lithium ion battery packet, and battery pack 7, which is done, to be vibrated
When test, referring to the placement status on vehicle, it is desirable that it is horizontal positioned, and is fixed on vibration test rack.And in reality
Battery pack 7 will carry out vibration test by specific acceleration, vibration frequency and vibration number in experiment, this fixture should be able to be effective
Vibration condition is transmitted to battery pack 7, so that it is met the requirement of vibration test parameter and efficiently completes test.This folder is required simultaneously
Tool needs to have enough stability and intensity, and fixture should be able to completely support vibration test and will not be to certainly in the whole process
Body dependency structure generates damage.When specific experiment, by 12 threaded holes 2 on rectangle bottom plate 1, this fixture is consolidated with bolt
It is scheduled on vibration mechine table top.Then battery pack 7 is promoted to above this fixture again, 7 bolt hole of battery pack is aligned and is carried
Battery pack 7 is fixed on this fixture with fixing bolt, can carry out vibration test by the arcuate socket 6 on plate 5.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, above structure
It all shall be regarded as belonging to the protection scope of the utility model.
