Description

Technical Field

[0001] This invention relates to the field of glass technology, specifically to a curved glass for a high-speed train driver's cab. Background Technology

[0002] The background technology of curved glass in high-speed train cabs stems from the dual requirements of modern high-speed trains for aerodynamic performance and driver visibility. Traditional flat glass is prone to wind resistance, turbulence, and wind noise during high-speed operation, and edge optical distortion can affect the driver's judgment. To overcome these defects, curved glass technology uses a precision hot bending process to process high-strength multi-layer composite glass into an arc that conforms to the streamlined shape of the train body, reducing the drag coefficient by about 20% and reducing rain and snow adhesion. The glass adopts a laminated structure, with an outer layer of chemically tempered glass to resist the impact of flying stones, a middle layer of polyvinyl butyral film to achieve penetration resistance, and an inner layer coated with a transparent conductive film to prevent fogging. In terms of optical design, the curved glass optimizes the radius of curvature through computer simulation to ensure that the light transmittance exceeds 90% and the distortion rate is less than 0.3% at different viewing angles. A nano-hydrophobic coating is used to make the water droplet contact angle greater than 110 degrees to improve self-cleaning ability. This technology integrates interdisciplinary achievements such as materials science, fluid mechanics, and optical engineering. Its production requires a segmented progressive hot pressing process in a constant temperature and humidity environment to avoid stress concentration inside the glass.

[0003] Most existing curved glass for high-speed train cabs has the following drawbacks: the lateral force generated by the crank-connecting rod mechanism used in the curved glass of high-speed train cabs causes the slider to press against the guide rail on one side, resulting in significant uneven wear of the guide rail; the traditional bolt fixing method forms a rigid connection between the glass edge and the window frame, and the vibration energy of the car body is directly transmitted to the glass without buffering, resulting in a severe stress concentration effect at the fastening point, which can easily cause the propagation of microcracks in the glass; in addition, the window system is continuously subjected to high-frequency vibrations in a specific frequency band during operation, and the existing structural design lacks an effective way to dissipate vibration energy, which further aggravates the instability of the system. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a curved glass for a high-speed train cab to solve the technical problems that affect the stability of the system, such as guide rail wear caused by lateral force, stress concentration caused by bolt fixing, and insufficient energy dissipation under high-frequency vibration.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a curved glass for a high-speed train cab, comprising a main body, a high-pressure outer glass disposed on one side of the main body, a slide rail disposed on one side of the high-pressure outer glass, a slider movably connected inside the slide rail, a pressure plate fixed at the bottom end of the slider, an inner glass movably connected inside the main body, and the inner glass being fixed to the slider, a rotating rod disposed inside the main body, a limit plate fixed to the outside of the rotating rod, a limit block disposed inside the inner glass, and the limit block cooperating with the limit plate.

[0006] By adopting the above technical solution, when the slide rail is activated, it pulls the slider installed inside it. The slider slides in the center of the main body, and because one end of the slider is fixed to the inner glass that moves inside the main body, the inner glass moves up and down inside the main body simultaneously as the slider slides. This guides the slider to move linearly along the central axis, avoiding the lateral force of the traditional crank connecting rod, resulting in symmetrical force distribution on the window frame, reduced wear, and reduced local stress concentration. In addition, the slide rail and slider system have a low static friction coefficient, allowing it to be stably suspended at any position on the movement trajectory.

[0007] Furthermore, a fixing plate is connected to the outside of the rotating rod, a groove is opened at the bottom end of the pressure plate, a setting plate is provided inside the main body, a movable cavity is opened inside the setting plate, multiple sets of metal pressure plates are fixed at the bottom end of the inner glass, and an arc-shaped groove that cooperates with the limiting plate is opened inside the limiting block.

[0008] By adopting the above technical solution, when the slider is moved to the appropriate position, the pressure plate fixed at the bottom will push the rotating rod. Because a fixed plate is provided at one end of the rotating rod, when the fixed plate is rotated, the rotational force will be transmitted to the limiting plate through the rotating rod. The limiting plate will rotate around the rotating rod as the axis, so that the limiting plate can squeeze the limiting block located inside the inner glass.

[0009] Furthermore, a base is provided at the bottom of the main body, the high-pressure outer glass is bonded to the slide rail with polyurethane adhesive, the slide rail has a groove inside that cooperates with the slider, and a fixing block that cooperates with the rotating rod is provided at the top of the setting plate.

[0010] By adopting the above technical solution, and because the limiting block has a fixed round rod inside to cooperate with the compression and self-locking of the limiting plate, it is possible to ensure that the inner glass can be braked synchronously when the slider is braked and locked downwards, preventing the inner glass from shaking during the operation of the main body. In addition, the fixing of the pressure plate can increase the limiting and locking of the inner glass. The bottom of the inner glass is also provided with multiple sets of metal pressure plates. When the metal pressure plates are in contact with the setting plate inside the main body, they can play a role in suppressing resonance transmission and reducing the risk of glass micro-cracks.

[0011] In summary, the present invention has the following advantages: The present invention uses a control console to start the slide rail to drive the slider to slide, the slider is connected to the inner glass to move it up and down, the slide rail guides linear motion to reduce wear, the system has a low coefficient of friction and can be suspended at any position, when the slider moves, the pressure plate pushes the rotating rod to drive the limiting plate to rotate, the limiting plate squeezes the limiting block in the inner glass to achieve self-locking and prevent the glass from shaking, the metal pressure plate at the bottom of the inner glass can suppress resonance transmission and reduce the risk of micro-cracks, this structure makes the slide rail wear uniform, and the metal pressure plate buffers vibration energy to avoid stress concentration and protect the glass.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0015] The embodiments of the present invention will now be described.

[0016] A type of curved glass for high-speed train cabs, such as Figures 1-8As shown, the device includes a main body 1, a high-pressure outer glass 3 on one side of the main body 1, a slide rail 5 on one side of the high-pressure outer glass 3, a slider 6 movably connected inside the slide rail 5, a pressure plate 11 fixed at the bottom of the slider 6, an inner glass 4 movably connected inside the main body 1, and the inner glass 4 is fixed to the slider 6, a rotating rod 7 is provided inside the main body 1, a limit plate 9 is fixed to the outside of the rotating rod 7, and a limit block 10 is provided inside the inner glass 4, with the limit block 10 cooperating with the limit plate 9. When the slide rail 5 is activated, it pulls the slider 6 movably mounted inside it. Since the slider 6 slides in the center of the main body 1, and because one end of the slider 6 is fixed with the inner glass 4 that moves inside the main body 1, when the slider 6 slides, it will simultaneously drive the inner glass 4 to move up and down inside the main body 1. This plays the role of the slide rail 5 guiding the slider 6 to move linearly along the central axis, avoiding the lateral force of the traditional crank connecting rod, symmetrically distributing the force on the window frame, reducing wear, and reducing local stress concentration. In addition, the slide rail 5 and slider 6 system have a low static friction coefficient and can be stably suspended at any position on the movement trajectory. For example, a fixing plate is connected to the outside of the rotating rod 7, a groove is opened at the bottom of the pressure plate 11, a setting plate 13 is provided inside the main body 1, a movable cavity 12 is opened inside the setting plate 13, multiple sets of metal pressure plates 14 are fixed at the bottom of the inner glass 4, and an arc-shaped groove that cooperates with the limiting plate 9 is opened inside the limiting block 10. When the slider 6 is moved to the appropriate position, the pressure plate 11 fixed at the bottom of the slider 6 will push the rotating rod 7. Because a fixing plate 8 is provided at one end of the rotating rod 7, when the fixing plate 8 is rotated, the rotational force will be transmitted synchronously to the limiting plate 9 through the rotating rod 7, and the limiting plate 9 will rotate around the rotating rod 7 as the axis, so that the limiting plate 9 can squeeze the limiting block 10 located inside the inner glass 4. For example, a base 2 is provided at the bottom of the main body 1. The high-pressure outer glass 3 and the slide rail 5 are bonded together with polyurethane adhesive. The slide rail 5 has a groove inside that cooperates with the slider 6. A fixing block 8 that cooperates with the rotating rod 7 is provided at the top of the setting plate 13. The limiting block 10 has a round rod fixed inside to cooperate with the compression and self-locking of the limiting plate 9. This ensures that when the slider 6 is braked and locked downwards, the inner glass 4 can also be braked simultaneously to prevent the inner glass 4 from shaking during the operation of the main body 1. The fixing of the pressure plate 11 can also increase the limiting and locking of the inner glass 4. The bottom of the inner glass 4 is also provided with multiple sets of metal pressure plates 14. The metal pressure plates 14 can suppress resonance transmission and reduce the risk of glass micro-cracks during the process of the inner glass 4 and the setting plate 13 inside the main body 1 being attached.

[0017] The working principle of this invention is as follows: When in use, after the main body 1 is installed by the staff, the high-pressure outer glass 3 is kept in a fixed state. When the main body 1 is in operation, the staff inside the main body 1 can electrically start the slide rail 5 inside the main body 1 through the control console set inside the main body 1. When the slide rail 5 is activated, it pulls the slider 6 that is slidably installed inside it. Since the slider 6 slides in the center of the main body 1, and because one end of the slider 6 is fixed to the inner glass 4 that is movable inside the main body 1, when the slider 6 slides, it will simultaneously drive the inner glass 4 to move up and down inside the main body 1. This allows the slide rail 5 to guide the slider 6 to move linearly along the central axis, avoiding the lateral force of the traditional crank connecting rod, ensuring symmetrical force distribution on the window frame, reducing wear, and reducing local stress concentration. In addition, the slide rail 5 and slider 6 system have a low static friction coefficient and can be stably suspended at any position on the movement trajectory. When the slider 6 is moved to the appropriate position, the pressure plate 11 fixed at the bottom will push the rotating rod 7. Because a fixed plate 8 is provided at one end of the rotating rod 7, when the fixed plate 8 is rotated, the rotational force will be transmitted to the limiting plate 9 through the rotating rod 7. The limiting plate 9 will rotate around the rotating rod 7 as the axis, so that the limiting plate 9 can press the limiting block 10 located inside the inner glass 4. Furthermore, because the limiting block 10 has a round rod fixed inside to cooperate with the squeezing and self-locking of the limiting plate 9, it can ensure that when the slider 6 is braked and locked downwards, the inner glass 4 can also be braked simultaneously to prevent the inner glass 4 from shaking during the operation of the main body 1. Furthermore, the fixing of the pressure plate 11 can increase the limiting and locking of the inner glass 4. The bottom of the inner glass 4 is also provided with multiple sets of metal pressure plates 14. During the process of the inner glass 4 and the setting plate 13 set inside the main body 1, the metal pressure plates 14 can play the role of suppressing resonance transmission and reducing the risk of glass microcracks. The above structure achieves less uniform wear on the slide rail 5, and the metal pressure plate 14 can buffer the vibration energy of the vehicle body, prevent it from being directly transmitted to the glass, prevent serious stress concentration effect at the fastening parts, and protect the glass.
