Description

Technical Field

[0001] The present invention belongs to the technical field of windshield profiles, and particularly relates to a rail transit windshield profile applicable to complex working conditions. Background Art

[0002] In the continuous development process of rail transit, the running speed of trains has been increasing, and the driving environment has become more and more complex and diverse. As a key component to ensure the safe and comfortable operation of trains, the windshield profile plays an important role in isolating the external airflow, reducing noise, and buffering the vibration between vehicles.

[0003] Currently, the main types of windshields include rubber windshields, mechanical external windshields, and folding shed windshields. The folding shed windshield usually consists of a metal frame and a rubber capsule. The traditional metal frame only plays the role of connecting the capsule and the carriage. In the complex working conditions of strong winds, it does not have the function of resisting pressure and is prone to bending. Summary of the Invention

[0004] Aiming at the problems mentioned in the background art, the purpose of the present invention is to provide a rail transit windshield profile applicable to complex working conditions to solve the problems mentioned in the above background art. [[ID=IS]]

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: [[ID=2t]]

[0006] A rail transit windshield profile applicable to complex working conditions includes a frame. Multiple sealed pressure-dividing cavities are opened in the frame. The length direction of the pressure-dividing cavity is perpendicular to the driving direction of the carriage. The number of pressure-dividing cavities close to the carriage gradually increases and the cross-sectional area of the cavity gradually decreases; the side of the frame close to the carriage is the windward side, and the side close to the capsule is the leeward side;

[0007] An installation frame two is installed on the side of the frame away from the carriage, and a capsule is further included. The capsule is installed on the installation frame two;

[0008] The installation frame two is L-shaped, and a slot is formed between the installation frame two and the frame. The installation part of the capsule is inserted into the slot;

[0009] A limiting clip in a U-shape and having a tendency to contract towards the opening side is further included. The limiting clip is sleeved outside the installation part, and one side of the limiting clip is inserted between the frame and the installation frame two.

[0010] As a preferred technical solution, the outer edge and outer corners of the frame are smooth and round.

[0011] As a preferred technical solution, a reinforcing rib is installed between the adjacent sides at the inner corner of the frame.

[0012] As a preferred technical solution, the length of the reinforcing rib is greater than the thickness of the frame, and the thickness of the reinforcing rib is not greater than the thickness of the frame.

[0013] As a preferred technical solution, a mounting frame 1 is installed on the side of the frame close to the carriage, and the mounting frame 1 is fixedly connected to the carriage.

[0014] As an optimal technical solution, multiple sets of bolts are installed on the mounting frame 1, and multiple sets of mounting holes are installed on the corresponding carriage. The mounting frame 1 and the carriage are quickly installed through the bolts and mounting holes.

[0015] This invention proposes a rail transit windshield profile suitable for complex operating conditions. It utilizes multiple sealed, independent pressure-dividing chambers to disperse stress and enhance the windshield frame's wind resistance. The frame's outward-facing edges and corners are designed with smooth, rounded edges to reduce the risk of cracking or breakage due to stress concentration. Reinforcement ribs are also added to enhance the frame's deformation resistance. Mounting frames 1 and 2 enable quick installation of the frame, the carriage, and the capsule, saving time and effort.

[0023] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention, and are not to be construed as limiting the present invention.

[0024] Example 1

[0025] Reference Figures 1 to 5 , a rail transit windshield profile applicable to complex working conditions described in this embodiment includes a frame 1 and a capsule 2. The capsule 2 and the carriage are respectively installed on both sides of the frame 1. According to the driving direction rule of rail transit, the side of the frame 1 close to the carriage is the windward side, and the side close to the capsule 2 is the leeward side. A plurality of sealed pressure-dividing cavities 11 are opened in the frame 1. The length direction of the pressure-dividing cavity 11 is perpendicular to the driving direction of the carriage. The number of the pressure-dividing cavities 11 close to the carriage gradually increases and the cross-section of the cavity gradually decreases. A plurality of independent sealed pressure-dividing cavities 11 are constructed inside the frame 1. When subjected to strong wind force or bending force, the plurality of pressure-dividing cavities 11 can disperse stress and avoid stress concentration at a single part, resulting in deformation or damage of the profile. The cross-section of the pressure-dividing cavity 11 close to the windward side is relatively small and the number is relatively large, which can better resist wind pressure.

[0026] Preferably, the shape of the pressure-dividing cavity 11 is the same as that of the frame 1.

[0027] The outer edge and outer corners of the frame 1 are smooth and round. Compared with a right angle, the rounded corner can effectively reduce the stress concentration phenomenon. When subjected to wind load or bending force, the stress can be more evenly distributed on the frame 1, reducing the risk of cracks or fractures in the profile due to stress concentration.

[0028] Reinforcing ribs 3 are installed between the adjacent sides at the four inner corners of the frame 1. The length of the reinforcing rib 3 is greater than the thickness of the frame 1, and the thickness of the reinforcing rib 3 is not greater than the thickness of the frame 1.

[0029] Preferably, the length of the reinforcing rib 3 is 2-3 times the thickness of the frame 1, and the thickness of the reinforcing rib 3 is 0.5-1 times the thickness of the frame 1.

[0030] The reinforcing rib 3 can significantly improve the stiffness of the frame 1, just like adding a support beam in a building structure, enhancing its ability to resist deformation.

[0031] Mounting frames one 4 and mounting frames two 5 are respectively installed on both sides of the frame 1. The frame 1 is fixedly connected to the carriage and the capsule 2 through the mounting frames one 4 and the mounting frames two 5 respectively.

[0032] Specifically, multiple groups of bolts 41 are installed on the mounting frame one 4, and multiple groups of mounting holes are installed on the corresponding carriage. During installation, the corresponding mounting holes on the carriage are sleeved on the bolts 41, and can be quickly installed on the carriage by fastening with nuts.

[0033] Preferably, the mounting frame two 5 is L-shaped, a slot is formed between the mounting frame two 5 and the frame 1, the mounting part 21 of the capsule 2 is inserted into the slot, and it further includes multiple groups of U-shaped limiting clips 6 with a tendency to contract towards the opening side.

[0034] Preferably, the slot opening faces downward, and the mounting portion 21 is sleeved on the second mounting frame 5. The limiting clip 6 is sleeved on the outside of the mounting portion 21, wherein one side of the limiting clip 6 is inserted between the frame 1 and the second mounting frame 5, and further includes a fastener 7, which securely connects the limiting clip 6, the second mounting frame 5, and the mounting portion 21.

[0035] Because capsule 2 is large, it requires first limiting its position and then securing it during installation, which is time-consuming, labor-intensive, and difficult to install. Therefore, a second mounting frame 5 and a retaining clip 6 are added to facilitate quick installation. Specifically, during installation, mounting portion 21 is sleeved onto mounting frame 5, and retaining clip 6 is sleeved onto the outside of mounting portion 21. Retracting clip 6 initially and quickly secures mounting portion 21 under its own contraction force. Once capsule 2 is fully circumferentially secured, fastener 7 secures capsule 2, completing installation.

[0036] This device disperses stress through multiple sealed, independently separated pressure-dividing chambers 11, increasing the windshield frame 1's wind resistance. The outward-facing edges and corners of the frame 1 are smooth and rounded, reducing the risk of cracking or breaking due to stress concentration. Reinforcing ribs 3 are also added to enhance the frame 1's resistance to deformation. Mounting frames 1 (4) and 2 (5) enable quick installation of the frame 1, the vehicle compartment, and the capsule 2, saving time and effort.
