[0002] The existing widely used rail vehicles have become a convenient means of transportation for daily travel. The existing rail vehicle passenger room considers safety and air tightness, and the passenger room side window is mostly fixed. However, the driver's room is small, and in order to facilitate emergency escape, the demand for movable windows in the driver's room is increasing. Moreover, the opening angle and positioning of the movable window are required to be higher and higher.

[0003] The existing movable window structure mostly uses ordinary folding. Such folding does not have a limiting function and cannot stop at a certain required opening angle. However, the existing components that can control the opening angle of the window mostly use a pneumatic spring structure, but the pneumatic spring generally has a high failure rate and a short service life, which is not conducive to the stability of the product, and also has the problem of lubricating oil leakage and pollution of the surrounding environment. The ordinary folding is not associated with the pneumatic spring component, occupies installation space, and is not conducive to integration and modularization.

[0004] Therefore, under the premise of ensuring the strength and sealing of the window, the actual demand is met, and the present application provides a rail vehicle movable side window folding structure. SUMMARY

[0092] The track vehicle movable side window folding structure mainly includes a fixed part 1, a movable part 2, and a bead spring D.

[0093] And a pin shaft 3 is provided, which is used to connect the fixed part 1 and the movable part 2. The fixed part 1 is installed on the outer frame of the window, and the movable part 2 is installed on the inner frame of the window. Among them,

[0094] A circular groove is machined on the fixed part main plate A of the fixed part 1 as a bead spring mounting hole 14 for installing the bead spring D.

[0095] A limiting groove, i.e. a long groove 10, is machined on the movable part secondary plate C of the movable part 2. The long groove 10 cooperates with the bead spring D to fix the window at a preset angle.

[0096] As described above, the overall structure of this movable side window folding structure is simple, which can play a limiting role and also allow the window to be fixed at the desired position of the customer.

[0097] The fixed part 1 is machined, and a fixed part positioning protrusion 9A is provided on the middle of one side of the fixed part main plate A for positioning during folding installation.

[0117] The fixed part inclined slot 15A is opened on the fixed part 1, which facilitates the removal of the folder.

[0118] Three long grooves 10 are opened on the movable part 2, the spacing of the long grooves 10 depends on the required opening angle of the window. The depth of the long groove 10 can be determined according to the spring force of the pearl spring D and the opening and closing force of the window. The edges of the long groove 10 are chamfered, which can make the pearl spring D slide into the long groove 10 more smoothly, and the outer surface of the movable part 2 and the fixed part 1 can be painted or plasticized to meet the artistic requirements of the window.

[0119] The hinge needs to be pre-assembled with a brief introduction.

The pin shaft 3 is in clearance fit with the movable part 2, and the pin shaft 3 is in interference fit with the fixed part 1. A rubber hammer can be used to assist installation during installation. After the hinge is pre-assembled, it is installed on the window outer frame F and the window inner frame G. When installing the fastening screw E, thread locking glue can be applied to prevent loosening.

[0120] In summary, the hinge structure of the rail vehicle movable side window provided by the embodiment of the present application has the following advantages:

[0121] The overall structure is simple and practical, occupies small space, has high strength, and is easy to ensure the installation strength of the window, which is beneficial to ensure the air tightness of the window.
