Abstract
The utility model relates to a seal structure of a high-voltage distribution box of a new-energy automobile, and the structure comprises a distribution box body, a cover plate fixed on the outer surface of the distribution box body via a fastening piece, and a seal washer disposed between the distribution box body and the cover plate. A side part of the upper end of the distribution box body is provided with an overhanging edge which extends outwards. The seal washer is placed between the cover plate and the overhanging edge of the distribution box body. An end part of the cover plate is provided with a flanging which extends downwards to the overhanging edge of the distribution box body. An end part of the inner side of the overhanging edge of the distribution box body is provided with a boss which can protect the seal washer from sliding inwards. The flanging on the cover plate and the boss on the overhanging edge of the distribution box body can prevent the seal washer from sliding inwards or outwards. A through hole on the distribution box body is disposed on the overhanging edge of the distribution box body, so as to enable water or oil not to enter the distribution box body when the distribution box body is immersed in the water or the oil, and play a good waterproof effect. Accordingly, the seal structure is good in seal performance, convenient in installation, and long in service life.
Description
Technical field
The utility model relates to the hermetically-sealed construction of new-energy automobile high-tension distribution box.
Background technology
The sealing of the high-tension distribution box of using on pure electric automobile is all to realize by the seal washer that directly installs a waterproof between cover plate and casing additional.But in the assembling process of reality, thereby affected the rigging position of seal washer due to assembler's change, caused the bad situation of some regional seal to produce; Even if after having added the structures such as bolt, in the situation that installing force is inhomogeneous or long-term work, can cause seal washer to be extruded in installing force larger zone and expose casing, accelerate to consume and wearing and tearing, and the little regional seal packing ring of installing force inside contracts, and causes the situations such as poorly sealed.
Summary of the invention
The purpose of this utility model is exactly for defects, and the hermetically-sealed construction of the new-energy automobile high-tension distribution box of a kind of good seal performance, easy for installation, long service life is provided.
the technical scheme that its technical problem that solves the utility model adopts is: the hermetically-sealed construction that a kind of new-energy automobile high-tension distribution box is provided, comprise distributing box, by securing member be fixed on the cover plate of distributing box outer surface and be arranged on distributing box and cover plate between seal washer, described distributing box upper end one sidepiece has outward extending outwardly extending lip edge, described seal washer lining cover plate and distributing box outwardly extending lip along between, there is the flange that extends downward distributing box outwardly extending lip edge the end of described cover plate, the medial end on described distributing box outwardly extending lip edge is provided with the boss that prevents that seal washer from inwardly sliding.
Leave the gap between the flange inwall of described cover plate and the outer wall of seal washer.
The width in described gap is 5-8mm.
Described distributing box outwardly extending lip is along the through hole that has mounting fastener, has in the cover plate position corresponding with through hole the installing hole that passes securing member.
The utility model compared with prior art, beneficial effect is: seal washer lining cover plate and distributing box outwardly extending lip along between, flange on cover plate and distributing box outwardly extending lip are along upper boss, prevented that seal washer from inwardly or outwards sliding, through hole on distributing box is arranged on the distributing box outwardly extending lip along upper, can not enter in distributing box by through hole when guaranteeing distributing box immersion or oil, played good waterproof action, so sealing sealing structure performance is good, easy for installation, long service life.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in accompanying drawing:
Fig. 1 is the utility model structural representation.
Embodiment
as shown in Figure 1, a kind of hermetically-sealed construction of new-energy automobile high-tension distribution box, comprise distributing box 2, cover plate 1 and be arranged on distributing box 2 and cover plate 1 between seal washer 3, distributing box 2 upper end one sidepieces have outward extending outwardly extending lip along 2.1, the outwardly extending lip of cover plate 1 and/or distributing box has along 2.1 the groove of installing for seal washer 3, thereby with seal washer 3 lining between cover plate 1 and distributing box outwardly extending lip are along 2.1, simultaneously, the end of cover plate 1 has and extends downward the flange 1.1 of distributing box outwardly extending lip along 2.1, the distributing box outwardly extending lip is provided with boss 2.2 along 2.1 medial end.One end and the boss 2.2 of seal washer 3 are inconsistent, because seal washer is plastic material, in the situation that when seal washer is installed and long-term work, the seal washer of plastics can deform and expand to periphery, therefore to leave certain gap 4 between the flange inwall of the outer wall of the seal washer other end and cover plate, the flange 1.1 of cover plate of the present utility model and the distributing box outwardly extending lip boss 2.2 along 2.1 has prevented that seal washer 3 from inwardly or outwards sliding; But this gap 4 can not be too wide, and is too wide, although seal washer has the cover plate flange spacing, but can be outwards mobile, can not be too narrow, too narrow, can't stand the distortion of seal washer, so the width in its gap 4 is 5-8mm.
In order to strengthen the location between cover plate 1 and distributing box 2, adopt securing member 5 to add strong fix, have through hole 2.3 at the distributing box outwardly extending lip along 2.1, the position corresponding with through hole 2.3 at cover plate 1 has installing hole 1.2, and securing member 5 passes the installing hole, seal washer of cover plate and the through hole on outwardly extending lip edge successively.
Through hole 2.3 due to the distributing box mounting fastener is arranged on outwardly extending lip along on 2.1 again, can not enter in distributing box by through hole when guaranteeing distributing box immersion or oil, has played good waterproof, sealing function.
The above is described embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection range of the present utility model.
