Description

Technical Field

[0001] This utility model relates to the field of train head fairing technology, specifically an integrally molded fiberglass train head fairing with built-in reinforcing ribs. Background Technology

[0002] With the continuous development of modern railway transportation technology, train design must not only meet the requirements of high speed, safety, and comfort, but also consider the optimization of aerodynamic performance to reduce air resistance and improve train energy efficiency and stability. The fairing at the front of the train, as a key component, plays a crucial role in guiding airflow, reducing air resistance, and improving train operating efficiency.

[0003] Traditional train fairings are typically made of metal or composite materials and manufactured using a one-piece molding process. However, due to the complex shape of train fairings and the need to withstand the powerful airflow pressure generated at high speeds, a single structural design often struggles to balance strength, weight, durability, and aerodynamic performance. Therefore, to improve the overall performance of the fairing, many designs incorporate reinforcing ribs to enhance the fairing's pressure resistance and improve its stability.

[0004] The existing design of the train fairing reinforcement has certain shortcomings:

[0005] First, traditional reinforcing ribs often use simple connection methods and lack reasonable limiting components to ensure the stability and precise installation of the reinforcing ribs, which can easily lead to displacement or deformation of the reinforcing ribs, thereby affecting the aerodynamic performance of the fairing.

[0006] Secondly, many fairings have relatively simple reinforcing rib designs that fail to fully consider the stress distribution and structural strength under high-speed driving, which can easily lead to stress concentration and fatigue damage.

[0007] There is currently no effective solution to the aforementioned technical problems in the industry. Utility Model Content

[0008] To solve the above problems, this utility model provides the following technical solution:

[0009] An integrated fiberglass train head fairing with built-in reinforcing ribs includes an integrated fairing body made of fiberglass. The top of the fairing body has a positioning groove for mounting a windshield, and the rear of the fairing body has a communication port for connecting with the vehicle body. The inner top wall of the fairing body has a first groove near the front of the vehicle, and a first reinforcing rib is provided in the first groove. The first reinforcing rib is fixedly connected to the first groove by a plurality of bolt assemblies arranged at intervals. The inner bottom wall of the fairing body has a second groove, and a second reinforcing rib is provided in the second groove. The second reinforcing rib is fixedly connected to the second groove by limiting assemblies provided at both ends.

[0010] Preferably, the bolt assembly includes a bolt and a threaded sleeve, the first reinforcing rib has a countersunk hole, the threaded sleeve is embedded in the body of the flow guide, and the bolt passes through the countersunk hole and connects with the threaded sleeve.

[0011] Preferably, the limiting component includes a lever, a limiting block, and a guide post. The limiting block and the guide post are respectively disposed on both sides of the lever, and the limiting block faces the side of the second groove. A sliding groove is provided in the body of the flow guide cover at a position corresponding to the guide post, and the guide post is slidably disposed in the sliding groove.

[0012] Preferably, a spring is sleeved on the outer side of the guide post, and the two ends of the spring abut against the side wall of the lever and the outer wall of the slide groove, respectively.

[0013] Preferably, the top of the lever protrudes from the top of the second groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By setting the first and second reinforcing ribs, the structural strength and rigidity of the fairing body can be effectively increased, enabling it to withstand greater air pressure during high-speed driving, reducing deformation, extending service life, and ensuring the stability and reliability of the train head fairing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0024] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0025] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1 As shown in this embodiment, an integrally molded fiberglass train head fairing with built-in reinforcing ribs includes an integral fairing body 1 made of fiberglass. The top of the fairing body 1 has a positioning groove 2 for installing the windshield, and the rear of the fairing body 1 has a communication port 3 for connecting with the vehicle body. The fairing body 1 is made of resin as the matrix and glass fiber as the reinforcing material, and is processed by hand lay-up, molding, or winding.

[0027] The inner top wall of the fairing body 1, near the front of the train, has a first groove. A first reinforcing rib 4 is located within this groove, and the first reinforcing rib 4 is fixedly connected to the groove by multiple sets of bolt assemblies 5 arranged at intervals. Since high pressure is generated at the top of the train's front during high-speed operation, the placement of the first reinforcing rib 4 here helps to improve the pressure-bearing capacity of the top of the train's front, thereby enhancing the overall structural strength of the fairing and improving driving safety.

[0028] The inner bottom wall of the fairing body 1 is provided with a second groove, and a second reinforcing rib 6 is provided in the second groove. The second reinforcing rib 6 is fixedly connected to the second groove by limiting components 7 provided at both ends. The bottom of the fairing body 1 is the main load-bearing structure. The provision of the second reinforcing rib 6 here helps to improve its structural strength, thereby further enhancing the overall structural strength of the fairing.

[0029] The first reinforcing rib 4 and the second reinforcing rib 6 can be made of the same fiberglass material as the fairing body 1, or they can be made of high-strength and lightweight materials such as PDCPD and aluminum alloy. Their shapes can be made into rod-shaped or plate-shaped structures that match the internal contour of the fairing body 1.

[0030] like Figure 2 As shown, the bolt assembly 5 includes a bolt 51 and a threaded sleeve 52. The first reinforcing rib 4 is provided with a countersunk hole 53. The threaded sleeve 52 is embedded in the guide body 1. The bolt 51 passes through the countersunk hole 53 and is connected to the threaded sleeve 52.

[0031] like Figure 3 As shown, the limiting component 7 includes a lever 71, a limiting block 72, and a guide post 73. The limiting block 72 and the guide post 73 are respectively disposed on both sides of the lever 71, and the limiting block 72 faces the second groove. A sliding groove 74 is provided in the body of the flow guide shroud 1 at a position corresponding to the guide post 73, and the guide post 73 is slidably disposed in the sliding groove 74.

[0032] A spring 75 is sleeved on the outside of the guide post 73. The two ends of the spring 75 abut against the side wall of the lever 71 and the outer wall of the slide groove 74, respectively. The top of the lever 71 protrudes from the top of the second groove to facilitate the movement of the lever 71.

[0033] When installing the first reinforcing rib 4, first place the first reinforcing rib 4 in the first groove and align each countersunk hole 53 with the threaded sleeve 52. Then, screw the bolt 51 onto the threaded sleeve 52 to fix the first reinforcing rib 4 in the first groove. The first reinforcing rib 4 can improve the pressure resistance and bending resistance of the top of the fairing body 1, thereby improving the structural strength of the fairing body 1.

[0034] When installing the second reinforcing rib 6, first move the lever 71 towards the slide groove 74 to allow the guide post 73 to enter the slide groove 74, creating installation space for the second reinforcing rib 6. Then, place the second reinforcing rib 6 in the second groove. After releasing the lever 71, the guide post 73 returns to its original position under the action of the spring 75, and the limiting block 72 abuts against the upper side of the second reinforcing rib 6, thereby confining it within the second groove. The second reinforcing rib 6 helps improve the pressure resistance and bending resistance of the bottom of the fairing body 1, thereby further enhancing the structural strength of the fairing body 1.

[0035] The bolt assembly 5 and the limiting assembly 7 enable the rapid installation and disassembly of the first reinforcing rib 4 and the second reinforcing rib 6, simplifying the installation and maintenance process and improving production and repair efficiency.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
