Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 7, a schematic structural diagram of an embodiment of a precursor sealing member for new energy electric driving of the present utility model is provided, the precursor sealing member for new energy electric driving comprises a body 1, gaskets 3 are disposed on the left and right sides of the body 1, sealing strips 6 filled with sealing liquid are disposed in the body 1, liquid outlet holes 7 which penetrate through the gaskets 3 and are communicated with the sealing liquid in the sealing strips 6 are disposed on the left and right sides of the body 1, the liquid outlet holes 7 are taper holes, bosses 4 are disposed on the upper and lower sides of the body 1, grooves 5 are disposed between the bosses 4, and bumps 2 are symmetrically disposed on the left and right sides of the body 1.

The body 1 assemble in the recess of casing 9, body 1 lower terminal surface with the basal plane laminating of the recess of casing 9, body 1 on have unequal circular lug 2, body 1 medial surface with the recess medial surface interference laminating of casing 9, the interference ratio is 1.05-1.1, can guarantee reliably that body 1 install casing 9 after prevent the nature and drop, can make body 1 install the intermediate position of casing 9 simultaneously.

After the assembly of the shell 9 is completed, the body 1 is provided with a corresponding upper cover 8 on the upper end surface of the body 1, and the lower surface of the upper cover 8 is attached to the upper end surface of the body 1; a bolt connecting hole is formed between the upper cover 8 and the shell 9; fastening bolts, so that the lower surface of the upper cover 8 is attached to the upper surface of the shell 9; the lower surface of the upper cover 8 moves downwards to be compressed and attached to the upper end face 101 of the body 1 in the fastening process; and simultaneously, the bottom plane 302 of the groove of the shell 9 upwards supports the lower end face of the body 1 to be compressed and attached.

Further, in the fastening process, when the upper cover 8 moves downwards to compress the body 1, the inner and outer annular circular arc protrusions of the body 1 play a supporting role when the body 1 tilts, so that the body 1 can be effectively prevented from tilting and overturning in the compression process, and the compression sealing function of the body 1 is reliably ensured.

Further, in the fastening process, the sealing strip is pressurized to release the sealing liquid, which is typically sealing silicone grease, and under the action of the pressure, the sealing liquid fills the gap between the body 1 and the housing 9.
