Embodiment
Understand for the ease of persons skilled in the art and realize the utility model, now describing embodiment of the present utility model by reference to the accompanying drawings.
As shown in Fig. 1 to 5, the utility model provides a kind of battery of electric vehicle management system mounting casing, comprising: housing 2, and it is a rectangular box, thin-wall construction, and there is mounting ear both sides respectively, and there is opening the rear end of housing; Battery management system plate 3, it is arranged in housing, its side is provided with the first connector 4, second connector 5, when battery management system plate 3 is installed in housing, described first connector 4 and the second connector 5 stretch out outside housing by the opening of housing rear end, described first connector and the second connector outermost end distance housing outer end at least 5mm, wherein, first connector 4 is connected with battery pack, and the second connector 5 is connected with the master control in high-tension distribution box; End cap 1, it is arranged on the front end of housing.
Described housing is connected with end cap back-off, has the gap of 0.2-0.5mm between housing and end cap.
Two ends, the left and right medial surface of described housing is provided with installs gathering sill 6, for installing battery management system plate 3; The porch of described installation gathering sill 6 has oblique angle.The thickness of width slightly larger than circuit board of gathering sill 6 is installed, gathering sill 6 length is installed and runs through medial surface.Described housing, end cap are made of plastics.
Shell inner surface is provided with horizontal rib, to strengthen the intensity of housing.
There is several back-off structure end cap 1 side, to snap onto on housing 2.There is several horizontal rib end cap 1 inside, and rib is with location notch.There is the location notch coordinated with housing the position that each rib in side is corresponding.
According to embodiment of the present utility model, the rear end of housing has opening to be four, wherein three consistent size, and for the first connector, another size is slightly large, uses the second connector.Ear standing part is stretched out in the housing left and right sides, symmetrical.The upper surface of housing 2 is roughly plane.Be provided with longitudinal strengthening rib strip inside housing lower wall, its height 0.3-0.5mm, rib runs through whole base plane.The large oblique angle of rib two end band.
In addition, housing is upper and lower, rear wall inner surface is provided with horizontal strengthening rib strip, and the strengthening rib strip simultaneously near openend also has guide effect.The edge of four openings of rear surface with installation oblique angle, when making installation battery management system plate, to have guide effect to connector.Rear surface is provided with location structure near the left and right sides of opening, and this location structure is corresponding with " ear " of connector.
In addition, along there being oblique angle in housing forward end peristome, on above and below, opening portion, there is equally distributed slot respectively.The back-off of this hole and end cap fastens.
End cap is rectangle, thin-wall construction.Upper surface is smooth, and bottom is the square frame-shaped structure inside contracted.Inner homogeneous is distributed with several strengthening rib strips.Location notch is had in strengthening rib strip.Upper uniform several back-off outside the front and back of square frame-shaped structure, symmetrical placement.
Battery management system plate inserts bottom along the guiding mounting groove of housing, and the installation ear of connector and the square location of housing bottom are close to, and now battery management system plate is mounted to enclosure interior, and has located.Location notch in the rib of housing inner bottom part in the vertical direction to battery management system plate location, and has the gap of 0.2-0.5mm with board edge side in the horizontal direction.
The process of installing end cap is described below, and cover internal rib first blocks battery management system plate with the part of location notch, and the direction of adjustment end cap, makes the location notch of end cap sidewall coordinate with the location reinforcement of enclosure interior.Now, compress end cap downwards, the back-off on end cap is closely engaged with the button hole on housing.
Be connected with connector screw by battery management system plate, then the battery management system plate installed and connector are inserted housing in the lump, end cap inwardly, finally covers by connector direction.
The utility model holder housing is made of plastics, have reliable, easy accessibility is installed, with low cost, technique simple, joint space-efficient advantage.
Although depict the utility model by embodiment, but those of ordinary skill in the art know, when not departing from spirit of the present utility model and essence, the utility model just can be made to have many distortion and change, and scope of the present utility model is limited to the appended claims.
