The case lid includes upper cover body and lower cover；The size of the upper cover body by the side wall above the transverse slat with being surrounded Size be adapted；The lower cover is connected to the lower section outer ring of the upper cover body, its size and the chi surrounded by the transverse slat It is very little to be adapted；After covering case lid, the upper cover body covers the suitable for reading of the card lid mechanism, and the lower end of the lower cover is fitted in institute State on casing.

The cooperation of clamped cover structure and case lid makes the better tightness of battery case, and sealing gasket is set above transverse slat, with upper cover body Combine closely, sealing gasket and extraneous contact area are small, and fire line is preferable.

As the technical scheme of optimization, the side wall is structure as a whole with the transverse slat, and the upper end of the side wall is first downward Flip up again, form the transverse slat.

As the technical scheme of optimization, the casing is structure as a whole with the card lid mechanism, the box top opening The tank wall at place flips up to form the side wall.

Lower box, the side wall of upper box and clamped cover structure and transverse slat are an entirety, and globality is preferable.

As the technical scheme of optimization, the transverse slat is surrounded by the equal circle of width, is easy to the installation of case lid.

As the technical scheme of optimization, the top surface opening shape of the casing is identical with the top surface shape of the casing, opens The box top partial width of a circle is identical with the width of the transverse slat on the outside of mouthful, the outward flange of the transverse slat and the casing Corresponding side wall is in the same plane.

It is in the same plane to cover the side wall of lower cover and the corresponding side wall of casing after case lid, overall leveling, reasonable profit Use space.

As the technical scheme of optimization, the casing includes upper box and lower box, and the upper box and lower box are one Body structure, for the upper box to adapt to the shape of its internal electrical part arrangement, the lower box is cuboid.

As the technical scheme of optimization, the upper box is that the side of the cuboid formed is being upwardly extended by the lower box The shape of several outstanding cuboids on face.

As the technical scheme of optimization, the cross section of the upper box is sticked to form by two rectangular long sides "convex" shaped, the left side of "convex" shaped and rear side are protruded outside the lower box.

The shape installation space of casing is compact, "convex" shaped structure increase inner space.

As the technical scheme of optimization, the bottom of the lower box is provided with leg, and the leg is located at the upper box and dashed forward The lower section in source.

As the technical scheme of optimization, the leg includes bottom plate and supporting plate；Bottom surface of the bottom plate along the casing Stretch out；The supporting plate is modification of right-angled triangle plate, and two right-angle side is bonded the upper surface of the bottom plate and described respectively The side of lower box, stand bar structure make casing more stable.

The utility model has the advantage of：Spaces compact, sealing and fire line are preferable.
