Distance of the case lid 20 relative to casing 10 is limited, so as to the first sealing ring 30 defined between case lid 20 and casing 10 exists
The degree that is squeezed of short transverse, it is to avoid the first sealing ring 30 is produced by excessive compression and makes the shearing force of its seal failure.
Maximum height of the height more than all spacing preiections 111 before the compression of first sealing ring 30, so that
After case lid 20 presses to casing 10, case lid 20 directly compresses and contacts (namely inner terminal and outermost end with highest spacing preiection 111
Spacing preiection 111), and the first sealing ring 30 is squeezed, realization is effectively sealed against.
First sealing ring 30 is affixed to the face of the second outer rim 21 and the molar of the second outer rim 21 coordinates, so that the first sealing
Will not be also shifted between the outer rim 21 of circle 30 and second.
First sealing ring 30 is affixed to Cheng Youyi, the face rectangular recess of the second outer rim 21, and first outer rim 11 is affixed to
A rectangular preiection 211 corresponding with the rectangular recess is formed on the face of the first sealing ring 30, by rectangular recess and square
Positioning of first sealing ring 30 in the second outer rim 21 is realized in the cooperation of shape projection 211.
Certainly, the variable amounts of the rectangular preiection 211 and rectangular recess, such as two, three etc..
Deform as one kind, first sealing ring 30 is affixed on the face of the second outer rim 21 and can be molded rectangular preiection 211,
And the first outer rim 11 is affixed on the face of the first sealing ring 30 and then correspond to shaping rectangular recess.
It is first that the first sealing ring 30 is convex as its sealing in the second outer rim 21, is made before case lid 20 is installed to casing 10
Rise in 31 insertion limited impressions.After case lid 20 and casing 10 are fastenedly connected, first sealing ring 30 be extruded and first
Realize reliably sealing between the outer rim 21 of outer rim 11 and second.
In the present embodiment, also include：The 3rd outer rim 12 circumferentially extended on the casing 10, the 3rd outer rim 12 is located at
The periphery of first outer rim 11；The 4th outer rim 22 for being circumferentially extended on the case lid 20 and being fitted with the 3rd outer rim 12,
4th outer rim 22 is located at the periphery of second outer rim 21；Second sealing ring 40, is arranged at the 3rd outer rim 12 and
Between four outer rims 22.By the first sealing ring 30 and the dual sealing functions of the second sealing ring 40, the reliability of sealing structure is improved
Property.
As shown in figure 1, the first outer rim 11 and the 3rd outer rim 12 have difference in height, equally, the second outer rim 21 and the 4th outer rim
22 have difference in height.The first outer rim 11 and the 3rd outer rim 12 with difference in height, can avoid dust or water droplet directly and quickly
Into in battery case, sealing property is further improved.
The first groove 121 for accommodating the second sealing ring 40 is formed in 3rd outer rim 12；4th outer rim 22 exists
With the second groove 221 that the second sealing ring 40 of receiving is formed on the corresponding position of the first groove 121.The He of first groove 121
Second groove 221 is used to position the second sealing ring 40, prevents it from outwardly or inwardly shifting.3rd outer rim 12 and
After four outer rim 22 is fitted, second sealing ring 40 is compressed in the groove 221 of first groove 121 and second, and realization can
By sealing.
Before case lid 20 is installed to casing 10, first the second sealing ring 40 is filled in the first groove 121, in casing 10 and case
When lid 20 is fastened, the second sealing ring 40 clamp-ons the second groove 221.Or, first the second sealing ring 40 is filled in the second groove
221, when casing 10 and case lid 20 are fastened, the second sealing ring 40 is clamp-oned in the first groove 121.The second last sealing ring 40 is
Sealing is realized between three outer rims 12 and the 4th outer rim 22.
In the present embodiment, the sealing ring 40 of first sealing ring 30 and second obtains good position-limited box in sealing structure
Compression ratio is controlled, by the first sealing ring 30 and the collective effect of the second sealing ring 40 so that the degree of protection of battery case can
IP67 is met, so as to meet national standard and market needs.
Connecting hole 50 is formed respectively in 3rd outer rim 12 and the 4th outer rim 22；Bolt or screw sequentially pass through the 3rd
The connecting hole 50 of outer rim 12, the connecting hole 50 of the 4th outer rim 22 and the casing 10 and the case lid 20 are fastenedly connected.
Obviously, above-described embodiment is only intended to clearly illustrate example, and not to the restriction of implementation method.It is right
For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or
Change.There is no need and unable to be exhaustive to all of implementation method.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
