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 continuously increasing, and the driving environment has become more and more complex and diverse. As a key component to ensure the safety and comfort of train operation, 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 roof windshields. The folding roof windshield usually consists of a metal frame and a rubber capsule. The traditional metal frame only serves to connect the capsule and the carriage. In complex working conditions with 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.

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

[0006] A rail transit windshield profile applicable to complex working conditions includes a frame. A plurality of sealed pressure-dividing cavities are provided inside the frame. The length direction of the pressure-dividing cavity is perpendicular to the running 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.

[0007] As a preferred technical solution, the outer edge and outer corners of the frame are smooth and rounded.

[0008] As a preferred technical solution, reinforcing ribs are installed between adjacent sides at the inner corners of the frame.

[0009] 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.

[0010] As a preferred technical solution, an installation frame one is installed on the side of the frame close to the carriage, and the installation frame one is fixedly connected to the carriage.

[0011] As a preferred technical solution, a plurality of bolts are installed on the installation frame one, and a plurality of installation holes are installed on the corresponding carriage. The installation frame one and the carriage are quickly installed through the bolts and the installation holes.

[0012] As a preferred technical solution, 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.

[0013] As a preferred technical solution, the second mounting frame is L-shaped, and a slot is formed between the second mounting frame and the frame. The mounting portion of the capsule is inserted into the slot.

[0014] As a preferred technical solution, it further includes a U-shaped limiting clip with a tendency to contract toward the opening side. The limiting clip is sleeved outside the mounting portion, and one side of the limiting clip is inserted between the frame and the second mounting frame.

[0015] A rail transit windshield profile applicable to complex working conditions proposed by the present invention disperses stress through multiple groups of independently sealed pressure-dividing cavities, increases the wind resistance of the windshield frame, sets the outer edge and outer corner of the frame to smooth round edges and rounded corners, reduces the risk of cracks or fractures in the profile due to stress concentration, and adds reinforcing ribs to enhance the anti-deformation ability of the frame. The first mounting frame and the second mounting frame can achieve rapid installation between the frame and the carriage and the capsule, saving time and effort.

[0023] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference signs denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring 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.

[0024] Embodiment 1

[0025] Referring 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 provided in the frame 1. The length direction of the pressure-dividing cavities 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 cavities 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 pressure-dividing cavities 11 close to the windward side have a relatively small cross-section and a relatively large number, 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, a 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 mounting frames two 5 respectively.

[0032] Specifically, multiple groups of bolts 41 are installed on the installation frame one 4, and multiple groups of installation holes are installed on the corresponding carriage. During installation, the corresponding installation holes on the carriage are sleeved on the bolts 41, and the frame 1 can be quickly installed on the carriage by fastening with nuts.

[0033] Preferably, the installation frame two 5 is L-shaped, a slot is formed between the installation frame two 5 and the frame 1, the installation part 21 of the capsule 2 is inserted into the slot, and there are also multiple groups of U-shaped limit clips 6 which have a tendency to contract towards the opening side.

[0034] Preferably, the opening of the slot faces downward, and the installation part 21 is sleeved on the installation frame two 5. The limit clip 6 is sleeved outside the installation part 21, and one side of the limit clip 6 is inserted between the frame 1 and the installation frame two 5. There is also a fastener 7 which makes the limit clip 6, the installation frame two 5 and the installation part 21 fixedly connected.

[0035] Since the capsule 2 is large in volume, it is time-consuming and laborious to limit the position first and then fix it during installation, and it is difficult to install. Therefore, the installation frame two 5 and the limit clip 6 are added to help with quick installation. Specifically, during installation, the installation part 21 is sleeved on the installation frame two 5, and then the limit clip 6 is sleeved outside the installation part 21. The limit clip 6 preliminarily limits the installation part 21 quickly under its own contraction force. After the circumferential direction of the capsule 2 is all preliminarily limited, the capsule 2 can be fixed by the fastener 7 to complete the installation.

[0036] This device disperses stress through multiple groups of sealed and independent pressure-dividing cavities 11, increases the wind resistance of the windshield frame 1, sets the outer edge and outer corners of the frame 1 towards the outside as smooth round edges and rounded corners, reduces the risk of cracks or fractures in the profile due to stress concentration, and adds reinforcing ribs 3 to enhance the anti-deformation ability of the frame 1. The installation frame one 4 and the installation frame two 5 can achieve the quick installation between the frame 1 and the carriage and the capsule 2, saving time and effort.
