[0002] With the rapid development of my country's economy, the railway industry has also developed rapidly, and passengers have higher and higher requirements for the functionality, comfort and safety of railway products. The 160 km / h concentrated power EMU has been widely operated on various sections. In order to improve the comfort and aesthetics of the 160 km / h concentrated power EMU, a 200 km / h concentrated power EMU has been developed. The window structure of the 200 km / h concentrated power EMU is required to be the same as that of the 350 km / h standard EMU, with the window glass flush with the body and the window frame not exposed. At present, the installation environment of the 350 km / h standard EMU is an aluminum profile body, and bonding is the main and only force-bearing mode of the window structure. Although the strength meets the design requirements, the safety and firmness are relatively poor.

[0034] In this embodiment, a car window is installed on a carbon steel car body of a 200 km / h power-concentrated EMU. The car window includes a glass component 1, an adhesive 13, a window inner frame 2, a window outer frame 3, and a rivet nut 14. The glass component 1 is connected and fixed to the window inner frame 2 by the adhesive 13. A plurality of countersunk screws 15 are arranged on the outer circumference of the window inner frame 2. A plurality of rivet nuts 14 are installed on the inner circumference of the window outer frame 3. The plurality of rivet nuts 14 are respectively connected to the plurality of countersunk screws 15 of the window inner frame 2.

[0035] Install multiple mounting structures on the four sides of the window outer frame 3 respectively; place the car window on the vehicle body window, adjust the window position so that the window is evenly positioned in the upper, lower, left and right positions of the vehicle body window, and the glass component 1 of the car window is basically flush with the surface of the vehicle body; connect and fasten the mounting plates 4 of the multiple mounting structures to the vehicle body B-beam 18 around the vehicle body window; keep the tightening bolts 5 in a loose state; measure the flatness of the glass component 1 on the outside of the vehicle body and the surface of the vehicle body, adjust the position of the slider 11, and adjust the vehicle window to move up and down, left and right, and forward and backward until the flatness of the glass component 1 and the surface of the vehicle body meets the requirements; adjust the tightening bolts 5 on all mounting structures so that they are all tightened on the window outer frame 3, and tighten the locking nuts 7 and the tensioning bolts 6 on all mounting structures; after the window is installed, apply sealant to the gap between the vehicle body window and the window.

[0036] In the embodiment, the glass component 1 is connected and fixed to the inner window frame 2 by adhesive 13, and the adhesive 13 plays an absolute force bearing role, and the bonding grade is A1. Countersunk screws 15 are distributed on the outer circumference of the inner window frame 2. The inner circumference of the outer window frame 3 is processed with a circular hole, and a rivet nut 14 is installed at the circular hole. The countersunk screw 15 in module one is connected with the rivet nut 14, and module one and module two are combined together. The rivet nut 14 and the countersunk screw 15 are both well known and commonly used in the art.

[0037] See attached Figure 4 and 5 The outer side of the window frame 3 is processed with a slider mounting hole 23, and the size of the slider mounting hole 23 is larger than the size of the slider 11, so that the slider 11 can be installed into the window frame 3 from the slider mounting hole 23. The side of the outer circumference of the window frame 3 is processed with a through hole 21, and the tension bolt 6 passes through the hollow structure of the top bolt 5 and enters the hollow structure 20 of the window frame 3 through the through hole 21 and is threadedly connected with the threaded hole 22 of the slider 11. The slider 11 can be adjusted up, down, left, right, front, and back inside the window frame 3, and each position has an adjustment amount of 3mm. In order to facilitate the operation of the slider 11 after it is installed in the window frame 3, a handle 17 is installed on the slider 11. The slider 11 is inside the window frame 3, and the left and right directions are limited by the limit screws 25, and the up and down directions are limited by the profile and pressure plate 16 of the window frame 3.

[0038] See attached Figure 6 The bending structure of the pressing plate 16 is L-shaped stainless steel. The pressing plate 16 is provided with a limit screw 25, a second bolt hole 26, a handle hole 27, a limit bolt mounting hole 28 and a rivet mounting hole 29. The pressing plate 16 is fixed to the window outer frame 3 through the rivet 24 and the rivet mounting hole 29. The limit bolt mounting hole 28 is used to install a limit bolt to limit the left and right movement of the slider 11. The handle hole 27 is used to install the handle 17.

[0039] A plurality of mounting plates 4 are arranged on all four sides of the vehicle window. Since the length of the vehicle window is greater than the height, the number of mounting plates 4 used on the upper and lower sides of the vehicle window is greater than the number of mounting plates 4 used on the left and right sides of the vehicle window.

[0040] The material of the mounting plate 4 is Q235 angle steel, with a specification of 3mm×30mm×40mm. A 10mm×18mm oblong hole (i.e., bolt hole 1) is opened on one side of the angle steel with a side length of 30mm, which is used to connect with the body B-beam 18 through bolts, so that the upper, lower, left, and right positions of the window can be adjusted, while avoiding the use of adjustment pads. A 8mm×30mm×30mm reinforcement block 19 is locally welded on one side of the angle steel with a side length of 40mm, and a M16mm threaded through hole is opened in the center of the reinforcement block 19. The tightening bolt 5 passes through the oblong hole and the threaded through hole and is pressed on the pressure plate 16 outside the window outer frame 3, and the tightening bolt 5 gives the window outer frame 3 an outward thrust. A Φ8mm hollow structure is opened in the center of the tightening bolt 5, so that the M8mm tensioning bolt 6 passes through the hollow structure, and passes through the pressure plate 16 and the window outer frame 3 to connect with the slider 11 in the window outer frame 3. When the tension bolt 6 is tightened with the slider 11, the slider 11 gives an inward thrust to the window outer frame 3, so that the double-bolt structure composed of the tension bolt 5 and the tension bolt 6 can realize the forward and backward movement of the vehicle window in the thickness direction.

[0041] The double-bolt structure can not only meet the requirements of air pressure load resistance, that is, the window surface has no permanent deformation and damage after being subjected to ±6000Pa air pressure load, but also meet the requirements of positive and negative pressure resistance, that is, the strength of the window meets the continuous positive and negative alternating pressure load, the window does not fall out, the glass component 1 of the window is not damaged, and the inner window frame 2 and the outer window frame 3 are not damaged. It also meets the requirements of impact and vibration performance under Class 1 A test conditions specified in the national standard (GB / T 21563). Through static strength analysis and type test verification, the double-bolt structure meets the strength requirements of the entire window, while avoiding the problems of failure of the adhesive bonding between the window and the body and the substandard bonding environment between the window and the body. Even if these two situations occur, the double-bolt structure can still meet the strength requirements of the entire window.

[0042] This embodiment is used for 200 km power concentrated EMUs, which have two window sizes, 1450 mm (width) × 750 mm (height) and 614 mm (width) × 750 mm (height). The utility model has been successfully applied to 200 km power concentrated EMUs, achieving the expected design effect.
