Detailed Description
Referring to fig. 1 to 5, the specific embodiment of the invention is that a novel lightweight outer windshield structure is arranged between two end walls between two adjacent vehicle bodies, the outer windshield structure comprises two windshield frames 1, an annular rubber plate 2, a middle frame 3 and a spring hanging device 4, the windshield frames 1 and the middle frame 2 are aluminum profile frames with the shapes consistent with the outer contours of the end walls, the middle frame 2 is arranged between the two windshield frames 1, the annular rubber plate 3 is connected between each windshield frame 1 and the middle frame 2, and sealing strips are arranged on the two windshield frames 1 and connected to the two adjacent vehicle body end walls through bolts 5. The windshield frame 1 is a square aluminum section, the outside size of the windshield frame 1 is the same as the outer contour of the end wall, the inner side of the windshield frame 1 is provided with a sliding groove 101, and a bolt is placed in the sliding groove 101 to connect the annular rubber plate 2, so that the connection is convenient and rapid. One corner of the outer side of the windshield frame 1, which is close to the annular rubber plate 2, is set to be a chamfer structure 102, the inner side of the chamfer is flush with the outer surface of the annular rubber plate 2, the windshield frame 1 is in smooth transition to the annular rubber plate 2, and the aerodynamic performance of the vehicle end is improved. The middle frame 3 is a square aluminum profile, and the external outline size of the middle frame 3 is slightly smaller than that of the windshield frame 1 and is consistent with that of the annular rubber plate 3. Annular rubber slab 2 adopts the mould pressing silica gel material, be integrated into one piece's "nearly" font structure, the cambered surface structure of design indent in the middle of the annular rubber slab 2, "nearly" font both sides one side passes through bolted connection with 1 medial surface of windshield frame, annular rubber slab 2 coats with 1 contact surface of windshield frame and seals glue, play sealed effect, the opposite side passes through bolted connection with 3 inboards of middle frame, annular rubber slab 2 coats with 3 contact surfaces of middle frame and seals glue, play sealed effect, nearly "font upside is towards the automobile body outside. Because the annular rubber plate 2 structure is adopted between the windshield frame 1 and the middle frame 3, the weight of the outer windshield is reduced, the outer windshield adopts a sealing structure, the pressure difference between the inner side and the outer side of the outer windshield is small, and the problems of outward turning, tearing, inner windshield shaking and the like of the outer windshield at the end of the high-speed motor train unit can be avoided.
For preventing outer windshield center frame flagging, center frame 3 respectively sets up two spring cable suspension devices 4 with windshield frame 1 at automobile body both sides face position, and spring cable suspension device 4's cable suspension spring one end is connected on center frame 3's pull ring fixing base, and the other end hangs on windshield frame 1's pull ring fixing base 401, and center frame 3 both sides cable suspension spring 402 symmetrical arrangement prevents center frame 3 flagging and keeps the intermediate position, alleviates the windshield simultaneously and rocks when high-speed operation.
For making outer windshield accord with the aerodynamics streamline structure, a corner that windshield frame 1 outside is close to annular rubber slab 2 sets up to chamfer structure 101, smooth transition when making wind to outer windshield from automobile body both sides, reduce the air current disturbance, the cambered surface structure that "nearly" font upside of rubber slab is the indent, air resistance carries out the water conservancy diversion through outer windshield annular rubber slab 2 indent cambered surface during high-speed operation, owing to adopt indent cambered surface structure, the air flows along outer windshield surface, improve vehicle end aerodynamics performance greatly.
