Detailed Implementation

[0040] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. The described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.

[0041] It should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0042] It should be understood that the terms "system," "apparatus," "unit," and / or "module" used in this application are a method of distinguishing different components, elements, parts, sections, or assemblies at different levels. However, if other terms can achieve the same purpose, they may be replaced by other expressions.

[0043] As indicated in this application and claims, unless the context clearly indicates otherwise, the words "a," "an," "a," and / or "the" are not specifically singular and may include the plural. Generally, the terms "comprising" and "including" only indicate the inclusion of expressly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements. An element defined by the phrase "comprising an..." does not exclude the presence of other identical elements in the process, method, product, or apparatus that includes the element.

[0044] In the description of the embodiments of this application, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more.

[0045] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0046] In the rail transit sector, high-speed trains face challenges such as tunnel pressure fluctuations and aerodynamic impacts from passing vehicles, placing higher demands on the sealing performance of their movable windows. Related technologies indicate that the sealing performance of movable windows in high-speed trains can cause interior noise, affecting passenger comfort, and air leakage can impact the interior temperature environment, leading to increased air conditioning energy consumption. The sealing performance of movable windows has become a bottleneck restricting the improvement of vehicle performance, thus requiring urgent optimization to enhance its effectiveness.

[0047] Please see Figure 1 The movable window disclosed in this application includes an inner frame 1, an outer frame 2, and a movable frame 3.

[0048] The inner frame 1 and the outer frame 2 combine to form the frame structure of the movable window. The inner frame 1 includes an inner frame beam 4, which divides the inner frame 1 into two parts. The space enclosed by the first side of the inner frame beam 4 and the inner frame 1 is a fixed area 11, and the space enclosed by the second side of the inner frame beam 4 and the inner frame 1 is a movable area 12. Fixed glass is installed in the fixed area 11, and movable frame 3 is installed in the movable area 12.

[0049] like Figure 1 As shown, the inner frame beam 4 is arranged horizontally, dividing the inner frame 1 into an upper inner frame and a lower inner frame. The space enclosed by the upper inner frame and the inner frame beam 4 is used to install the movable frame 3, and the space enclosed by the lower inner frame and the inner frame beam 4 is used to install the fixed glass. The inner frame beam 4 is not limited to being arranged horizontally; it can also be arranged in other ways to divide the inner frame 1 into two parts, such as being arranged vertically, dividing the inner frame 1 into a left inner frame and a right inner frame, all of which are within the scope of protection of this application.

[0050] For ease of subsequent description, this solution is illustrated using the example of the inner frame beam 4 dividing the inner frame 1 into an upper inner frame and a lower inner frame. The movable frame 3 is rotatably connected to the second side of the inner frame beam 4 to open or close the movable frame 3. When the movable frame 3 rotates downward, it opens; when it rotates upward to fit against the inner frame 1, it closes.

[0051] The movable window disclosed in this plan also includes a first sealing strip 5 and a second sealing strip 6.

[0052] Optionally, the first sealing strip 5 is installed on the upper inner frame and located on the side where the upper inner frame fits with the movable frame 3. The first sealing strip 5 is arranged along the circumference of the upper inner frame and is formed into a U-shape that fits the shape of the upper inner frame. The first sealing strip 5 is used to achieve a seal between the movable frame 3 and the upper inner frame.

[0053] A second sealing strip 6 is provided on the second side of the inner frame beam 4. The second sealing strip 6 is used to seal the movable frame 3 and the inner frame beam 4. The second sealing strip 6 is located at the open end of the U-shaped structure formed by the first sealing strip 5. The first sealing strip 5 and the second sealing strip 6 form an annular sealing strip.

[0054] After the movable frame 3 is closed, it compresses the first sealing strip 5, achieving a compression seal between the movable frame 3 and the upper inner frame. Simultaneously, the movable frame 3, parallel to the second side of the inner frame crossbeam 4, compresses the second sealing strip 6, achieving a compression seal between the movable frame 3 and the inner frame crossbeam 4. The annular sealing strip effectively seals the movable frame 3 and the inner frame 1, ensuring the airtightness of the movable window and reducing the constraint of the movable window on vehicle performance improvement.

[0055] The movable window disclosed in this solution has a first sealing strip 5 set in the inner frame 1 and a second sealing strip 6 set in the inner frame crossbeam 4. The first sealing strip 5 and the second sealing strip 6 are fixed structures and do not rotate with the movable frame 3. This can reduce interference of the movable frame 3 during rotation, reduce the difficulty of opening and closing the movable frame 3, and at the same time reduce the wear of the first sealing strip 5 and the second sealing strip 6, delay the aging of the first sealing strip 5 and the second sealing strip 6, extend the service life of the first sealing strip 5 and the second sealing strip 6, and ensure the sealing effect.

[0056] Optionally, the inner frame 1 has a first mounting groove, and the inner frame crossbeam 4 has a second mounting groove. The first and second mounting grooves are interconnected to form an annular groove. The annular sealing strip formed by the first sealing strip 5 and the second sealing strip 6 is installed in the annular groove.

[0057] The annular groove includes three groove walls, at least one of which is engaged with the annular sealing strip.

[0058] Please see Figure 3The annular groove has its opening facing inwards. A slot is provided on the groove wall near the outside of the carriage. The annular sealing strip includes a snap-fit ​​protrusion 8 that engages with the slot. The annular sealing strip is engaged with the annular groove through the slot that mates with the snap-fit ​​protrusion 8. Optionally, along the plane perpendicular to the inner frame 1, the protrusion has a triangular cross-section, and the slot also has a triangular cross-section.

[0059] To improve the sealing performance of the annular sealing strip, a sealing protrusion 7 is provided on the side of the annular sealing strip away from the outside of the carriage. For example... Figure 3 and Figure 4 As shown, a sealing protrusion 7 is provided on the side of the first sealing strip 5 that is in contact with the movable frame 3, and a sealing protrusion 7 is also provided on the side of the second sealing strip 6 that is parallel to the side of the first sealing strip 5 where the sealing protrusion 7 is provided. Optionally, a sealing protrusion 7 may also be provided on the side of the second sealing strip 6 that is pressed and sealed with the movable frame 3.

[0060] Continue reading Figure 3 and Figure 4 A waterproof strip 9 is provided on the side of the annular sealing strip corresponding to the groove opening near the outside of the carriage. The waterproof strip 9 is tightly attached to the second side of the inner frame crossbeam 4 and extends between the glass of the movable frame 3 and the second side of the inner frame crossbeam 4. The waterproof strip 9 is used to prevent external moisture from entering the annular groove. The waterproof strip 9 and the snap-fit ​​protrusion 8 are located on the same side of the annular sealing strip.

[0061] Optionally, the first sealing strip 5 and the second sealing strip 6 are high-elasticity ethylene propylene diene monomer (EPDM) sealing strips, and the first sealing strip 5 and the second sealing strip 6 have high resilience.

[0062] Optionally, the first sealing strip 5 and the second sealing strip 6 include a snap-fit ​​portion and a sealing portion. The snap-fit ​​portion is used to connect with the annular groove, and the sealing portion is used to achieve a seal. To ensure the connection strength between the snap-fit ​​portion and the groove, the snap-fit ​​portion is made of solid rubber; to ensure the sealing performance and resilience of the sealing portion, the sealing portion is a hollow foam structure.

[0063] This solution alters the cross-sectional shape and structural distribution of the first sealing strip 5 and the second sealing strip 6. The optimized sealing strips significantly improve elasticity and fit, enabling the movable windows to maintain a stable seal even under conditions of high-speed air pressure fluctuations and high-frequency opening and closing. This reduces interior noise, air leakage, and air conditioning energy consumption, ensuring stable interior air pressure during high-speed train operation. Ultimately, this improves passenger comfort and equipment reliability, filling the technological gap where existing movable windows cannot meet the requirements of high-speed, high-airtightness scenarios.

[0064] In other embodiments, the first sealing strip 5 and the second sealing strip 6 are solid rubber structures.

[0065] Optionally, the annular sealing strip is vulcanized around the entire circumference.

[0066] The movable frame 3 includes glass and a movable crossbeam 31, which is located at the end where the movable frame 3 is rotatably connected to the inner frame crossbeam 4. The movable crossbeam 31 is glued to the glass and rotatably connected to the inner frame crossbeam 4.

[0067] Optionally, the glass of the movable frame 3 is double-layered glass 32, and the fixed glass is also double-layered glass 32. The space between the double-layered glass 32 is a vacuum structure. The double-layered glass 32 structure can also reduce noise and improve sealing to a certain extent.

[0068] There are several ways to rotatably connect the movable crossbeam 31 to the inner frame crossbeam 4. Optionally, such as... Figure 2 As shown, the inner frame beam 4 is located between the fixed glass and the glass of the movable frame 3. The inner frame beam 4 includes an adhesive part for connecting to the fixed glass, a mounting part for installing the second sealing strip 6 between the fixed glass and the glass of the movable frame 3, and a connecting part for connecting to the movable beam 31. Optionally, the adhesive part, the mounting part, and the hinge part are also included.

[0069] The hinge portion includes a connecting portion disposed along the plane direction of the inner frame 1 and a first hinge portion 41 connected to the connecting portion;

[0070] The movable crossbeam 31 includes a second hinge portion 311, which is hinged to the first hinge portion 41.

[0071] The hinged part is hinged to the second hinged part 311 through the first hinged part 41 to realize the rotational connection between the movable crossbeam 31 and the inner frame crossbeam 4.

[0072] like Figure 3 As shown, along the plane where the middle frame is located, the first hinge part 41 is an arc-shaped groove, and the second hinge part 311 is an arc-shaped protrusion. The arc-shaped protrusion extends into the arc-shaped groove to realize the hinge between the first hinge part 41 and the second hinge part 311.

[0073] The movable crossbeam 31 includes a sealing portion parallel to the connecting portion, and there is a gap between the sealing portion and the connecting portion, where a leakage point may also form. To solve the leakage problem here, the inner frame crossbeam 4 optionally includes a third sealing strip 10, which is installed on the connecting portion and is used to achieve a seal between the connecting portion and the sealing portion.

[0074] Optionally, the third sealing strip 10 is a EPDM rubber sealing strip.

[0075] To further optimize the sealing effect between the sealing part and the connecting part, optionally, a sealing strip 101 is provided on the connecting part.

[0076] The sealing strip 101 can be a siliconized strip. The sealing strip 101 is connected to the connecting part by snap-fit. Specifically, the connecting part is provided with a slot, and the sealing strip 101 has a snap-fit ​​strip that mates with the slot.

[0077] The movable window disclosed in this solution provides multiple seals for the movable window through the cooperation of the first sealing strip 5, the second sealing strip 6, the third sealing strip 10 and the sealing strip 101, which effectively solves the problem of insufficient sealing caused by a single seal in related technologies. The first sealing strip 5 and the second sealing strip 6, the third sealing strip 10 and the sealing strip 101 are used to seal different positions, realizing multi-point sealing and multi-position sealing, reducing sealing blind spots.

[0078] The movable window disclosed in this solution also includes an auxiliary crossbeam 102, which is fixedly connected to the inner frame crossbeam 4;

[0079] The auxiliary crossbeam 102 includes a V-shaped groove with the opening of the V-shaped groove facing the movable frame 3. The movable frame 3 includes a slot corresponding to the position of the V-shaped groove, and an S-shaped spring 103 is provided between the slot and the V-shaped groove.

[0080] When the movable frame 3 opens, it compresses the S-shaped spring 103. The S-shaped spring 103 deforms between the V-shaped groove and the slot, causing the movable frame 3 to close. The S-shaped spring 103 applies a restoring force to the movable frame 3, assisting in closing the movable frame 3.

[0081] In some embodiments, the auxiliary crossbeam 102 is bolted to the inner frame crossbeam 4. In this solution, the auxiliary crossbeam 102 and the inner frame crossbeam 4 are connected in a detachable manner, which provides good stability and facilitates the disassembly and replacement of the auxiliary crossbeam 102.

[0082] The auxiliary crossbeam 102 has an installation groove at the position of the bolt hole corresponding to the bolt. A fourth sealing strip 104 is embedded in the installation groove. The fourth sealing strip 104 serves two purposes: firstly, it seals the bolt hole to prevent external dust and moisture from entering the bolt hole; secondly, it serves a decorative purpose to enhance the appearance of the carriage.

[0083] Secondly, this application also proposes a high-speed train, including a movable window, which is the movable window described in any of the above-mentioned schemes.

[0084] Since the movable window has the aforementioned technical effects, high-speed trains with this movable window also have the same technical effects, which will not be elaborated here.

[0085] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed, and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. The scope of this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described application concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
