Description
Technical field
The present invention relates to a kind of cabinet and use the battery case of the cabinet.
Background technique
The vehicles of the electric car as a new generation, become the hot spot of exploitation with its energy-saving and environment-friendly advantage.Battery case
It is typically mounted on the chassis of electric car, for placing the power battery of electric car, due to closer apart from ground, often
By the pollution and erosion of floor-dust, ponding, therefore battery case must have certain IP degree of protection, can guard box
Interior battery is not damaged.
As electric car field is constantly developed, people have higher requirement to the IP degree of protection of battery case, such as
Authorization Notice No. is that the Chinese utility model patent of CN205452396U discloses a kind of battery case with waterproof construction, the electricity
Pond case includes upper cover and lower box, and upper cover and lower box are all made of flange bending structure, wherein cover rim downward bending twice
Bending under bending, upper cover flanging and the second upper cover under sequentially connected first upper cover is formed, the edge of lower box is first to varus
After upward bending, when killing still further below after outward flanging, formed sequentially connected lower box in-flanges, bending on lower box,
Side and lower box flanging, bending, that is, box side on lower box, lower box side plate top and lower box are killed at the top of lower box
Top kills the case dental structure that side constitutes lower box.There is sealing strip, outside upper cover between upper cover flanging and lower box flanging
Flange is fixedly connected by fastener with nut strip with lower box flanging.
Above-mentioned battery case, upper cover flanging is fastened by bolts part with lower box flanging and nut strip is fixedly connected, and is
Guarantee the sealing effect between upper cover flanging and lower box, it is necessary to tighten screw bolt and nut item, make upper cover flanging and under
Sealing strip between cabinet flanging is by sufficiently large extruding force.But since upper cover flanging and lower box flanging are equal
For lamina structure, the intensity of cabinet and upper cover is lower, in extruding force biggish by screw bolt and nut item, upper cover flanging
Extrusion deformation can be generated with lower box flanging, causes poorly sealed between upper cover flanging and lower box flanging, is caused
Poor sealing effect between lid and lower box.
Summary of the invention
The purpose of the present invention is to provide a kind of cabinet, hold to cabinet when solving that cabinet is connect with upper cover in the prior art
Easily deformation occurs and the technical issues of cause poor sealing effect between upper cover and cabinet.The object of the invention is also to provide one kind
Use the battery case of the cabinet.
To achieve the above object, the technical scheme is that
A kind of cabinet, including box side, box side top kill downwards when formation cabinet first kills, and cabinet first is pressed
The lower end outward bending on dead side forms cabinet flanging, and one end that the separate cabinet first of cabinet flanging kills side inwardly kills
When formation cabinet second kills, cabinet flanging and cabinet second kill bilayer of the side formation for connecting with upper cover flanging
Connecting plate.
Cabinet flanging and cabinet second kill the corresponding perforation offered for installing fastener on side.
Cabinet flanging kills side with cabinet first and is vertically arranged.
The box side of the cabinet is wholely set with box baseplate, and one in adjacent two tanks side plate is equipped with crimp,
Another welded connecting in the crimp and adjacent two tanks side plate.
A kind of battery case, including cabinet and upper cover, upper cover include upper lid top panel, and the edge of upper lid top panel bends downward to be formed
The lower end outward bending of upper cover lower flange, upper cover lower flange forms upper cover flanging, and cabinet includes box side, box side top
End kills downwards when formation cabinet first kills, and the lower end outward bending that cabinet first kills side forms cabinet flanging, case
The separate cabinet first of external flange kill while one end inwardly kill while form cabinet second and kill side, cabinet flanging and case
Body second kills double-deck connecting plate of the side formation for connecting with upper cover flanging.
Double sealing structure is equipped between upper cover and cabinet, cabinet first kills side and the top of box side and forms case tooth
Structure is equipped with the first sealing structure between upper lid top panel and case dental structure, the is equipped between cabinet flanging and upper cover flanging
Two sealing structures.
One end downward bending of the separate upper cover lower flange of upper cover flanging is formed for being located at cabinet flanging periphery
The outer flaring of upper cover.
Cabinet flanging kills side with cabinet first and is vertically arranged.
Upper cover flanging, cabinet flanging and cabinet second kill correspondence on side and offer for installing wearing for fastener
Hole, upper cover and cabinet pass through the fastener being installed in perforation and are fixedly connected.
The box side of the cabinet is wholely set with box baseplate, and one in adjacent two tanks side plate is equipped with crimp,
Another welded connecting in the crimp and adjacent two tanks side plate.
The beneficial effects of the present invention are: box side top kills downwards when formation cabinet first kills in the present invention,
The outside bending in lower end that cabinet first kills side forms cabinet flanging, and the lateral ends of cabinet flanging inwardly kill side and formed
Cabinet second kills side, and box side, cabinet first is killed to be integrally formed when, cabinet flanging and cabinet second kill and be set
It sets, and cabinet flanging and cabinet second kill side and form the double-deck connecting plate, compared with prior art, the cabinet in the present invention
Structural strength is higher, and for the double-deck connecting plate when connecting with upper cover flanging, the double-deck connecting plate and upper cover flanging are able to bear foot
Enough big extruding forces will not generate extrusion deformation, and then guarantee the sealing effect between upper cover and cabinet.
As a further improvement of the present invention, battery case has double sealing structure, between upper lid top panel and case dental structure
First sealing structure is set, second seals structure is equipped between cabinet flanging and upper cover flanging, is further ensured that sealing effect
Fruit.
Further, one end of the separate upper cover lower flange of upper cover flanging bends downward to form the outer flaring of upper cover, upper cover
When being connect with cabinet, the periphery of upper cover outer cover edge cover flange outside the enclosure, and then between upper cover flanging and cabinet flanging
Structure protected.
