[0030] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the sealing structure for the movable window of the EMU window of this embodiment includes a movable window frame 2, which is rotatably installed on the window frame of the vehicle body wall via a rotating structure 5, and the movable window frame 2 is embedded with a sealing strip 3 along the circumferential direction, and the sealing strip 3 located outside the movable window frame 2 extends to form an extrusion portion 31, and the cross-section of the extrusion portion 31 is an annular structure 311; when the movable window frame 2 is rotated toward the window frame until it is in a closed state, the annular structure 311 is deformed and pressed between the movable window frame 2 and the window frame.

[0032] By setting the extrusion portion 31 of the sealing strip 3 as an annular structure 311, the annular structure 311 is not affected by the installation portion when it is deformed under force, and the annular structure 311 is easy to deform under force, thereby effectively ensuring the smooth closing of the movable window and effectively ensuring stable and reliable sealing performance after closing.

[0033] The sealing strip 3 is embedded and fixed with the movable window frame 2 via the mounting portion 32 , and the mounting portion 32 is located in a vertical direction of the compression direction of the annular structure 311 .

[0034] In this embodiment, the sealing strip 3 is installed via the mounting portion 32 and is extruded and sealed via the extrusion portion 31. The two parts have relatively independent functions and are used for installation and sealing respectively without affecting each other. In particular, the mounting portion 32 is located in a direction perpendicular to the clamping direction, which effectively avoids the influence of the mounting portion 32 on the clamping and ensures that the extrusion portion 31 is smoothly deformed by force when the movable window is closed.

[0035] A teardrop-shaped hole 312 is provided at the center of the annular structure 311 . The width of the teardrop-shaped hole 312 is smaller than its height. The pressing direction of the annular structure 311 is consistent with the width direction of the teardrop-shaped hole 312 .

[0036] In this embodiment, by setting the center of the annular structure 311 of the extrusion part 31 as a teardrop-shaped hole 312, the relatively small width direction of the teardrop-shaped hole 312 bears the pressing force when the movable window is closed, effectively ensuring the smoothness of the closing operation.

[0037] The height dimension of the water drop-shaped hole 312 is 1.3-1.8 times of the width dimension, which can effectively ensure and take into account the sealing performance and stress deformation performance of the sealing strip 3 .

[0038] The annular structure 311 is a circular structure in shape, the upper part of the teardrop-shaped hole 312 is a semicircular structure arranged concentrically with the circular structure, and the lower part of the teardrop-shaped hole 312 extends toward the mounting portion 32 to form an acute angle; while taking into account the stress deformation and sealing performance, the structural stability of the sealing strip 3 itself is effectively guaranteed.

[0039] The movable window frame 2 is provided with a T-slot 20 for the mounting portion 32 of the sealing strip 3 to be clamped and matched, so as to realize the rapid and reliable installation of the sealing strip 3 on the movable window frame 2; a movable vertical wall 201 is extended to form on the movable window frame 2 on the outer side of the opening of the T-slot 20, and the extrusion portion 31 is pressed between the movable vertical wall 201 and the window frame.

[0040] exist Figure 1 and Figure 2 In the illustrated embodiment, the rotating structure 5 is located at one edge of the bottom surface of the movable window frame 2. As shown in the figure, a rotating structure 5 is provided at the lower right corner. When the movable window is rotated to open relative to the window frame, the upper portion of the movable window frame 2 swings to the right relative to the window frame, and the lower left corner of the movable window frame 2 swings to the left relative to the window frame. In order to ensure a reliable seal between the movable window frame 2 and the window frame, the sealing strip 3 is arranged according to actual needs.

[0041] For the convenience of explanation, the movable window frame 2 is divided into an upper frame 21 and a lower frame 22, and the window frame is divided into an upper window frame 41 and a lower window frame 42. In actual use, the upper frame 21 and the lower frame 22 can be an integrated structure, and the upper window frame 41 and the lower window frame 42 can also be an integrated structure. In some vehicle window designs, a closed window is usually arranged below the movable window. At this time, the lower window frame 42 located below the movable window frame 2 can also be a partition frame in the middle of the window frame.

[0042] exist Figure 1 and Figure 2 In the figure, the left outer edge of the upper window frame 41 extends downward to form a static vertical wall 411, and the upper frame 21 located on the right side of the sealing strip 3 extends upward to form a dynamic vertical wall 201. When the movable window frame 2 is closed toward the window frame, the dynamic vertical wall 201 and the static vertical wall 411 approach each other to squeeze the sealing strip 3. In order to further ensure the sealing performance of the sealing strip 3, a concave structure 412 can also be provided on the lower side of the static vertical wall 411 facing the sealing strip 3. The concave structure 412 effectively reduces and prevents liquids such as rainwater from penetrating upward and inward.

[0043] exist Figure 2 and Figure 3 In the illustrated embodiment, a concave arc-shaped structure 421 conforming to the sealing strip 3 is provided on the lower window frame 42, and the lower frame 22 located on the left side of the sealing strip 3 extends downward to form a dynamic vertical wall 201. When the movable window frame 2 is closed toward the window frame, the dynamic vertical wall 201 approaches the lower window frame 42, driving the sealing strip 3 and the concave arc-shaped structure 421 to deform and resist each other; at the same time, the concave arc-shaped structure 421 also facilitates the downward and outward flow of liquids such as rainwater, and effectively reduces and prevents its upward and inward penetration.

[0044] The mounting portion 32 includes a strip-shaped body, and the two sides of the strip-shaped body are symmetrically concave to form a slot 322 that is clamped with the notch of the T-slot 20. The two side surfaces of the strip-shaped body located below the slot 322 extend downward and inward to form convex arc surfaces 323 respectively, and the bottom ends of the convex arc surfaces 323 on both sides are connected together to form a groove 325; a through hole 324 is formed in the strip-shaped body along the length direction.

[0045] In this embodiment, while effectively ensuring the structural strength of the installation portion 32 of the sealing strip 3, the reliability of the assembly between the installation portion 32 and the movable window frame 2 is effectively ensured.

[0046] In actual operation, a chamfer structure 202 may be provided at the notch of the T-slot 20.

[0047] The size of the strip body along the width direction is smaller than the size of the extrusion portion 31. Chamfered ridges 321 extend from the two side surfaces of the strip body where they meet the extrusion portion 31. The chamfered ridges 321 are located at the opening of the T-slot 20, effectively ensuring the structural stability and reliability of the sealing strip 3 after being assembled relative to the T-slot 20, making it difficult to fall out while remaining relatively fixed.

[0048] The mounting portion 32 is made of dense rubber, and the extrusion portion 31 is made of foam rubber. The density of the dense rubber is greater than that of the foam rubber. The mounting portion 32 and the extrusion portion 31 are formed into a sealing strip 3 of an integrated structure.

[0049] In this embodiment, the installation portion 32 of the sealing strip 3 composed of dense rubber has relatively high structural strength, which effectively ensures the structural stability and reliability of the sealing strip 3 and the movable window frame 2; the extrusion portion 31 of the sealing strip 3 composed of foamed rubber is relatively soft, which effectively ensures smooth deformation when subjected to force and effectively ensures the sealing performance after deformation.

[0050] The invention also comprises a glass assembly 1, a movable window frame 2 is sealed and mounted around the circumference of the glass assembly 1, and the movable window frame 2 and the glass assembly 1 constitute a movable window.

[0051] In actual use, the glass assembly 1 can be set as a double-layer hollow structure according to actual use requirements. It can be a double-glass structure or a composite structure combining glass and PC board.

[0052] The utility model divides the sealing strip 3 into an installation part 32 for installation and an extrusion part 31 for sealing. The two parts have relatively independent functions and do not affect each other, and are respectively used to achieve stable and reliable installation and effective and smooth deformation sealing.

[0053] The utility model effectively ensures smooth closing of the movable window and stable and reliable sealing performance after closing, and has good practicality.

[0054] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0055] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
