Circle is from top to bottom arranged between Battery case connection bolt nut and box top, and the tabletting is hard material tabletting, institute
The nut for stating bolt presses tabletting, and Battery case outer surface, the elastic washer central aperture surface are close in the elastic washer bottom surface
It is close to bolt outer circumference surface.
Further, the tabletting outer diameter is 2.5 times of Battery case bolt hole aperture, and internal diameter is the diameter of bolt
1.5 again.
Further, bolt hole corresponding with bolt is spot-facing on the Battery case.
Further, the bolt is countersunk head screw.
Further, the elastic washer is silicone gasket.
Compared with the existing technology, a kind of sealing structure of Battery case connection bolt described in the utility model have with
Lower advantage:
A kind of Battery case connection described in the utility model sealing structure of bolt, be set on bolt tabletting and
Silicone gasket is fixedly connected with cabinet upper-lower casing by bolt, at this point, on the one hand bolt realizes that the fastening of upper-lower casing connects
It connects, meanwhile, bolt is to tableting pressure, so that silicone gasket compressive deformation, so that silicone gasket bottom surface and upper housing top surface are close to,
The silicone gasket central aperture surface and bolt outer circumference surface are close to, and silicone gasket is filled with tabletting and spiral shell by compressive deformation at this time
Gap between bolt, cabinet realizes sealing, ensure that the leakproofness in the packet Life cycle of pond, ensures battery pack sealing.

State the concrete meaning of term in the present invention.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figure 1, a kind of Battery case connection sealing structure of bolt, including tabletting 3 and elastic washer 4, tabletting 3
The upper-lower casing for being set in cabinet 1 with elastic washer is fastenedly connected on bolt 2, it is however generally that, Battery case includes
Upper housing and lower case, upper housing and lower case are respectively provided with the connection eaves of connection along edge, and connection eaves is respectively provided with
It is bolted after using bolt hole, battery pack to place, 2 bottom end of bolt is fastened after passing through bolt hole, realizes the tight of upper-lower casing
It is solidly connected, in the present embodiment, the tabletting 3 for sealing is from top to bottom arranged in upper-lower casing with elastic washer 4 and connects with bolt 2
1 upper housing of nut and cabinet connection eaves between, the tabletting 3 is hard material tabletting, such as copper backing, stainless steel tabletting,
The material tabletting precision is high, and pulling force degree is strong, and flexible is not easily broken, and the nut of the bolt 2 presses tabletting 3, and tabletting 3 will
Elastic washer 4 is pressed on the connection eaves of upper housing, and 4 back pressure of elastic washer deforms at this time, guarantees that Battery case 1 is close in its bottom surface
Outer surface, 4 central aperture surface of elastic washer are close to 2 outer circumference surface of bolt；If bolt 2 uses countersunk head screw structure, such as attached
Shown in Fig. 1, the nut bottom surface of the countersunk head screw is pyramidal structure, and it is counter bore structure which, which corresponds to bolt hole, and fastening connects
