Description

Technical Field

[0001] The present invention relates to the technical field of train windshield aluminum profiles, and in particular to a high-strength train windshield aluminum profile. Background Art

[0002] In modern railway transportation, train speeds continue to increase, placing increasingly stringent demands on the performance of various train components. As a key component connecting train cars, the performance of train windshields directly impacts train safety, comfort, and overall energy efficiency. Early train windshields were mostly made of common materials, such as relatively low-strength aluminum alloys or other metals. As train speeds gradually increased, the shortcomings of these traditional windshield materials became increasingly apparent when faced with complex operating conditions such as the powerful airflow impact, body vibration, and frequent opening and closing operations generated by high-speed travel. Windshields made of ordinary materials cannot withstand the continuous pressure of high-speed airflow and are prone to deformation and damage. This not only affects the normal use of the windshield but also poses a threat to the safe operation of the train. Furthermore, traditional materials perform poorly in terms of sound insulation and sealing, failing to effectively block the noise and dust generated by train operation, thus degrading the passenger experience. Summary of the Invention

[0003] In order to solve the technical problems existing in the background technology, the present invention proposes a high-strength train windshield aluminum profile.

[0004] The present invention proposes a high-strength train windshield aluminum profile, comprising a strip-shaped base plate, a top block, and a clamping block. The strip-shaped base plate is placed horizontally, with side panels vertically connected to its two sides. The outer side walls of the two sets of side panels are each provided with an outwardly protruding curved plate. The cross-section of the aluminum profile is an axisymmetric figure.

[0005] A cavity is provided between the side plate and the connected arc-shaped plate, and multiple groups of positioning tubes are connected between the arc-shaped plate and the corresponding side plate. The multiple groups of positioning tubes are located in the container and are perpendicular to the side plate.

[0006] The two groups of top blocks slide vertically on the two groups of side plates respectively, and the inner side surfaces of the two groups of top blocks are both set as inclined surfaces, which are inclined from top to bottom toward the central axis of the cross section of the profile;

[0007] The two groups of clamping blocks are vertically located between the two groups of side plates and are respectively slidably connected to the inner side walls of the two groups of top blocks. The outer side surfaces of the two groups of clamping blocks are both configured as inclined surfaces, which are inclined from bottom to top toward the central axis of the cross section of the profile.

[0009] The upper parts of the inclined surfaces of the two groups of clamping blocks are laterally connected to multiple groups of guide rods, and the multiple groups of guide rods correspond to the multiple groups of positioning tubes one by one and are movably sleeved;

[0010] Two groups of bolts are provided on the strip-shaped base plate, and the two groups of bolts are respectively connected with the bottom threads of the two groups of top blocks. By rotating the bolts, the corresponding top blocks can be controlled to rise and fall.

[0011] Preferably, a plurality of groups of first reinforcing ribs are provided on the top of the strip-shaped substrate and between the side panels on both sides.

[0012] Preferably, multiple groups of first clamping grooves are provided on the bottom sides of the two groups of top blocks, and the first clamping grooves of each group correspond to and are clamped with the first reinforcing ribs one by one.

By rotating the bolt, the top block can be moved in the vertical direction of the side panel. As the top block moves upward, the two groups of clamping blocks can be brought closer, thereby clamping and positioning the glass plate.

[0024] 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.

[0025] like Figure 1-Figure 3 The high-strength aluminum profile for a train windshield shown in FIG. 1 includes a strip-shaped base plate 1, a top block 2, and a clamping block 3. The strip-shaped base plate 1 is placed horizontally, with side panels 101 vertically connected to its two sides. The outer side walls of both sets of side panels 101 are provided with outwardly protruding curved panels 102. The cross-section of the aluminum profile is an axisymmetric shape.

[0026] When a train is traveling at high speed, the windshield is subject to a variety of external forces, including airflow impact and body vibration. Therefore, the aluminum profile must have sufficient strength to withstand these external forces and ensure the stability and safety of the windshield structure.

[0027] A cavity is defined between the side plate 101 and the connected curved plate 102. Multiple sets of positioning tubes 104 are connected between the curved plate 102 and the corresponding side plate 101. The multiple sets of positioning tubes 104 are located in the container and are perpendicular to the side plate 101.

[0028] The two groups of top blocks 2 are respectively slid vertically on the two groups of side plates 101.

The threaded part of the bolt is threadedly connected to the top block 2. By rotating the bolt, the top block 2 can be moved in the vertical direction of the side plate 101. As the top block 2 moves upward, the two groups of clamping blocks 3 can be brought closer, thereby clamping and positioning the glass plate. A sealing strip is provided between the two groups of clamping blocks 3, and the clamping tightness of the two groups of clamping blocks 3 can be controlled by the feed amount of the bolt.

[0034] The frame's cross-section is streamlined to reduce airflow resistance. Sealing grooves are located along the frame's edges for installing sealing strips to ensure a tight seal on the windshield. The grooves' size and shape are carefully designed to fit snugly with the strips, ensuring a secure seal while facilitating installation and replacement.

[0035] Preferably, a plurality of groups of first reinforcing ribs 103 are provided on the top of the strip-shaped substrate 1 and between the side panels 101 on both sides to enhance the strength of the profile.

[0036] Preferably, the bottom sides of the two groups of top blocks 2 are provided with multiple groups of first slots 201 , and each group of the first slots 201 corresponds to and engages with the first reinforcing ribs 103 one by one, thereby preventing the top blocks 2 from being damaged by the first reinforcing ribs 103 .

[0037] Preferably, the bottoms of the two groups of clamping blocks 3 are connected with a clamping plate 301, and the bottom sides of the two groups of clamping plates 301 are provided with multiple groups of second clamping grooves 302, and each group of the second clamping grooves 302 respectively correspond to and clamp with the first reinforcing ribs 103 one by one, which can limit the clamping blocks 3 so that the clamping blocks 3 can only move left and right in the cross section of the profile.

[0038] Preferably, the outer side walls of the two groups of top blocks 2 are vertically provided with a first guide member 202, and the inner side walls of the two groups of side panels 101 are vertically opened with a first guide groove 105. The first guide members 202 of the two groups of top blocks 2 are engaged with the first guide groove 105 of the corresponding side panel 101, playing a guiding role and being able to limit the moving direction of the top block 2 on the side panel 101.
