Dissipate, the requirement of higher just is proposed to the security performance of pure electric coach, safe skylight need to be equipped with, is multiplied when critical condition occurs
Visitor can be escaped by safe skylight.
《Passenger train plan safety requirements》II grades of mandatory requirement and III level car set emergency escape Hatch Opening.Withdraw Hatch Opening
Refer to only in case of emergency for passenger as the opening on the roof of escape hatch or floor, i.e., safe skylight and floor go out
Mouthful.Seats, which are less than or equal to 50 people, need to set 1, and seats are more than 50 people and set 2, and the requirement of emergency escape hatch is arranged at ground
On plate and roof, due to setting the emergency escape hatch structure that can be opened from inside and outside portion complicated in floor in a vehicle, position is difficult to
Meet the requirements, thus the common form that the safe skylight for being installed on passenger car head cover is emergency escape hatch.
The manufacture craft of the safe skylight of electric motor coach currently on the market is mainly：Skylight hole above roof skin turns over
Side, in the corner incised notch mouth of skylight hole, by flange, the mode of beaing makes by hand, and four sections of arc panels are welded at the arc of corner.Should
Mode heavy workload, and make unsightly, it is poor that uniformity ensures, stitching portion be easy to cause leak.Therefore, safe skylight
Structure requires further improvement, and lifts the leakproofness of safe skylight, prevents rainwater etc. from leaking into car body, causes the things such as battery short circuit
Therefore.
Utility model content
The utility model technical issues that need to address are to provide a kind of safe skylight of new structure, improve safe skylight
Aesthetic measure, improve the leakproofness of uniformity and stop portion, while solve the consistency problem of skylight seam allowance specification.
To solve the above-mentioned problems, technical solution is used by the utility model：
A kind of electric motor coach vehicle safety skylight, sets on the carbody canopy of the electric motor coach and is used to install safe skylight
Opening, the safe skylight include the mounting seat being installed in carbody canopy opening and pass through articulated shaft and mounting seat phase
Hinged skylight cover, the mounting seat are included outside by the nested skylight seam allowance being installed in opening of vehicle body and by roof
Portion is installed on opening outer and the base outline border to match with skylight seam allowance.
Technical solutions of the utility model further improvement lies in that：The skylight seam allowance is overall punch forming, including with
The vertical edges of opening fit along the seam allowance side wall to fit and positioned at the lower end of seam allowance side wall and with the bottom surface of carbody canopy
Seam allowance flange.
Technical solutions of the utility model further improvement lies in that：The seam allowance side wall and the vertical edges of carbody canopy opening
Between by sealing glue sticking, by sealing glue sticking and seam allowance flange between the bottom surface of the seam allowance flange and carbody canopy
Also mutually fixed by fixing bolt between carbody canopy.
Technical solutions of the utility model further improvement lies in that：The base outline border is overall punch forming, including with
Outline border flange that the upper surface of carbody canopy fits and upper along the outline border side wall for setting sealing joint strip, on the outline border side wall
Also set up the axle bed being connected with articulated shaft.
Technical solutions of the utility model further improvement lies in that：Pass through sealing between the outline border flange and carbody canopy
Glue sticking, press fit between the seal groove that sealing joint strip and the skylight cover edge is set.
Technical solutions of the utility model further improvement lies in that：The fluid sealant is epoxy resin structural adhesive, acrylic acid
One kind in structure glue, PU structural adhesive, structural silicone adhesive.
By adopting the above-described technical solution, the technological progress that the utility model obtains is：
A kind of electric motor coach vehicle safety skylight of the utility model, has the advantages that reasonable in design, easy for installation, adopts
With overall stamping forming skylight seam allowance and base outline border, it is controlled the uniformity of product, by strengthening each unit interface
The leakproofness at place, has prevented seepy question.
The utility model combines sealing glue sticking using overall stamping forming component, does not splice gap, does not have
Risk is welded, while is mutually fixed by fixing bolt between seam allowance flange and carbody canopy, further enhancing the jail of installation
Solidity.
