Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the part sectional view of the utility model Windshield mounting structure embodiment one.As shown in Figure 1, Windshield mounting structure comprises: Windshield 1, L shape transitional frame 2, car body frame 3 and the bolt 4 for connecting L shape transitional frame 2 and car body frame 3.
Wherein, L shape transitional frame 2 comprises the first side 21 and the second side 22; Adjacent with Windshield 1 side for bonding Windshield 1, first side 21 inside the L shape turning of L shape transitional frame 2, the second side 22 is adjacent with Windshield 1 lee face.
Adjacent with car body frame 3 outside the L shape turning of L shape transitional frame 2, car body frame 3 comprises establishes the boss 31 of Windshield and the bearing surface 32 crossing with boss 31 for card; Wherein, the second bottom surface, side 22 of L shape transitional frame 2 is adjacent with the windward side of boss 31; First side, side 21 of L shape transitional frame 2 is adjacent with bearing surface 32; Bolt hole 41 is provided with in first side 21 of L shape transitional frame 2 and boss 31; L shape transitional frame 2 is connected by the bolt 4 being located in bolt hole 41 with car body frame 3.
The Windshield mounting structure that the utility model embodiment provides, comprises Windshield 1, L shape transitional frame 2, car body frame 3 and bolt 4.Wherein car body frame 3 is positioned at the front end of EMU or aircraft, for fixedly mounting Windshield, is a part for car body or aircraft skin, generally non-dismountable.Therefore, structural adhesion first can be adopted to be bonded in by Windshield 1 inside the L shape turning of L shape transitional frame 2, then the L shape transitional frame 2 of bonding Windshield 1 is fixed on car body frame 3 by bolt 4.The thickness general control of structural adhesion in 7 millimeter, when there is certain error in the size of L shape transitional frame or Windshield, the thickness of adjustable structure glue.Optionally, other colloids can be adopted to carry out bonding, the present invention does not do any restriction to this yet.
Because the cure time of structural adhesion is relatively long; and it is all higher to the requirement of operating environment, humidity temperature; usually multiple L shape transitional frame 2 for subsequent use can be got in advance ready; directly L shape transitional frame 2 for subsequent use can be bonded together with Windshield 1 for subsequent use; thus when Windshield 1 occurs cracked; change in installation in reality; dismantle after splitting broken Windshield 1; without the need to waiting for the solidification of colloid; directly bonding L shape transitional frame 2 and Windshield 1 can be fixed on car body frame 3 by bolt 4, decrease the replacement cycle.
Concrete, when Windshield 1 is bonded in inside the L shape turning of L shape transitional frame 2, four sides of Windshield 1 are adjacent with the first side 21 of L shape transitional frame 2, and the lee face of Windshield 1 is adjacent with the second side 22.When L shape transitional frame 2 and car body frame 3 are fixed, the second side 22 of L shape transitional frame 2 is adjacent with the windward side of boss 31, and the first side 21 of L shape transitional frame 2 is adjacent with bearing surface 32, by bolt 4 inserting bolt hole 41, thus Windshield and car body frame is fixed together.
In Fig. 1, bolt hole 41 is only schematic diagram, the restriction of its size not to bolt hole 41 size of the present invention.Optionally, the first side of L shape transitional frame is provided with multiple bolt hole, is evenly distributed on four limits of transitional frame.Same, in Fig. 1, Windshield is only schematic diagram, the restriction not to Windshield shape.Optionally, Windshield can be pairglass, or compound glass is composited, and Windshield also can be coated with protective film.
Structural adhesion adhesion by adopting thickness adjustable in the utility model embodiment, make Windshield that time error regulating power is installed stronger, junction aesthetic property is stronger, and L shape transitional frame and car body frame multi-surface contact,, there is not the risk of local deformation in uniform force, the Windshield mounting structure that the utility model embodiment is provided is equally applicable to complicated wrapround windscreen, in reality processing, only L shape transitional frame need be made man-hour to have identical curved surface with Windshield adding.
The Windshield mounting structure that the utility model embodiment provides, first Windshield is bonded on L shape transitional frame, again L shape transitional frame being bolted on car body frame, by avoiding Windshield to be directly bonded on car body frame, decreasing the replacement cycle of Windshield, avoid the wasting of resources, by the adhesion mode adopting thickness adjustable, make Windshield install time error regulating power comparatively strong, junction is attractive in appearance, and uniform force, there is not the risk of local deformation.
