Description

Technical Field

[0001] The utility model relates to the technical field of vehicle gangways, and particularly relates to a side guard plate structure of a gangway and a panel thereof. Background Art

[0002] Rail vehicles usually use a flexible gangway at the connection of two carriages for passengers to pass through and protect their safety. In order to avoid exposing the internal structure of the gangway in front of passengers, which may cause safety problems, and at the same time to enhance the aesthetic appearance of the vehicle interior, the gangway usually includes a side guard plate assembly for covering these internal structures and forming a coordinated appearance with the interior decoration of the carriage.

[0003] For the side guard plate, it is required to have a certain ability to withstand the squeezing of passengers leaning on it. At the same time, like the flexible windshield of the gangway, when the two carriages move relative to each other, such as when the distance between the carriages becomes longer or shorter, or when the carriages roll or nod relative to each other, it should be able to provide corresponding elongation or shortening amounts and deformation amounts suitable for rolling and nodding to compensate for the relative movement between the carriages. The side guard plate structure includes a panel and a side guard plate movement mechanism that allows the panel to move. Among them, the panel is the main functional part and undertakes the aforementioned main functions.

[0004] There are mainly two solutions for the side guard plate panel of the existing gangway. In the first solution, the panel is usually made of a rigid material such as an aluminum plate. Since the aluminum plate is a rigid part, it is difficult to have a large change in its length and width. Therefore, in the existing solution, usually two or three aluminum plates are overlapped and installed, and the side guard plate movement mechanism is used to change the overlapping amount between the aluminum plates to adapt to the relative movement between the carriages.

[0005] In the second solution, the panel is usually made of prefabricated plates with different arcs. During the running of the vehicle, the side guard plate movement mechanism is used to forcibly change the arc of the panel, and the change in the arc compensates for the change in the distance between the train carriages caused by the relative movement between the carriages.

[0006] Since the rail train will pass through various curves during operation, and is also affected by different road conditions (such as uphill and downhill), as well as the movement of the train coupler and wheel wear, etc., there will be various relative movements between the carriages, such as stretching, compression, side roll, nodding, etc. These relative movements cause corresponding width changes, torsion, etc. in the panel of the side guard plate structure of the gangway. For the first solution, since the panel is made of rigid material, only the overlapping of multiple panels can be used to compensate for the relative movement between the train carriages. Therefore, there will be gaps between the panels and friction and noise caused by mutual extrusion; in some extreme cases, the gap will become so large that it may catch the fingers, clothes, bags, etc. of passengers, resulting in unpredictable risks; and the extrusion friction will damage the surface of the panel, and the noise will affect the passenger comfort. For the second solution, since the panel adopts a curved design, a three-dimensional mold is required for manufacturing, resulting in high manufacturing costs. Moreover, during the actual operation of the train, the side guard plate structure of the gangway always follows the relative movement of the train carriages. There is a force in the panel to straighten or bend the panel in terms of the curvature. This force does not directly cause stretching through the panel surface for the panel, but causes bending of the panel, deteriorating the force condition of the panel and affecting the service life of the panel. Summary of the Invention

[0007] The purpose of the present utility model is to solve at least one of the above problems and / or other problems existing in the prior art.

[0008] To achieve the above purpose, according to one aspect of the present utility model, a panel of a side guard plate assembly for a vehicle gangway is provided. The panel is manufactured to be integrally flat and extend in the length direction, and the panel includes a central portion located at the center of the panel in the width direction, two side portions located on both sides of the central portion in the width direction of the panel, and two transition portions respectively extending obliquely between the central portion and the corresponding side portion. The central portion is flat and has a first thickness, and the thicknesses of the two side portions are both smaller than the first thickness.

[0009] It should be noted that in this article, the "width direction" of the panel (the left-right direction in Figure 1 、 2 corresponds to the traveling direction of the vehicle. The "length direction" of the panel (in Figure 1The vertical direction (up and down in the figure) corresponds to the height direction of the vehicle. In this solution, since the panel is manufactured to be flat as a whole, compared with the first solution of multiple panels in the prior art, it can effectively solve the friction, noise caused by the gaps and mutual extrusion between the panels, and the risk of clamping passengers. Compared with the second panel with a curved surface shape, the flat panel is not prone to bending force on the panel, significantly improving the stress condition of the panel and increasing the service life of the panel. Moreover, such a flat panel does not require a three-dimensional solid mold for manufacturing, reducing the manufacturing difficulty and cost. At the same time, the panel also includes two side parts with a thickness smaller than that of the central part, so that the function of adapting to and compensating for the movement between the carriages can be achieved through the deformation of these two thinned side parts (such as being wound, unwound, twisted, etc.) via the deformation of the panel. Of course, as described below, the transition part connecting the side part and the central part and even the flat central part can also be designed to be deformable, such as being wound (it should be noted that the panel is flat as a whole when manufactured, and in the installed state and during vehicle driving, the panel may be in various shapes under different forces, such as being wound at both ends and partially flexed, etc.). And, in this solution, by providing two transition parts, the sudden change in thickness between the central part and the thinned side part and the resulting weak part are avoided. This solution uses a flat panel with a simple structure, which is easy to manufacture and has a low cost on the one hand, and on the other hand, adjusts the flexibility of the panel through the setting of different thickness parts, realizes the function of the panel being wound and compensating for the movement between adjacent carriages, and at the same time, the relatively thick central part can also meet the strength required to withstand the forces such as passengers leaning and squeezing.

[0010] According to an example of the present invention, the two side parts have the same second thickness, and the second thickness is smaller than the first thickness. In this solution, since the thicknesses of the two side parts are the same, the manufacturing and assembly of the panel are simpler and more convenient without the need to distinguish between the two sides.

[0011] According to an example of the present invention, the panel includes a first plane constituting one surface of the panel, a second plane parallel to the first plane, two third planes located on both sides of the second plane in the width direction of the panel, and two fourth planes respectively connecting the second plane and the third plane. The distance between the first plane and the second plane in the thickness direction of the panel is the first thickness, and the distance between the first plane and the third plane in the thickness direction is the second thickness, and the first plane, the second plane, the third plane, and the fourth plane extend straight in the length direction. This solution defines the structure of the panel from another angle. From this solution, it can be seen that the panel is a flat plate shape composed of flat planes, and there is no problem of bending force that the curved surface panel in the prior art is prone to, and it is simple to manufacture and has a low cost.

[0012] According to an example of the present utility model, at least two side portions of the panel are configured to be woundable. Since at least two side portions can be wound and deformed, the panel can be mounted on a side guard movement mechanism capable of winding at least two side portions of the panel. The panel can be wound or loosened as the relative movement of the carriages occurs, so as to adapt to the relative movement between the carriages. According to an example of the present utility model, the two transition portions are also configured to be woundable, or both the two transition portions and the central portion are configured to be woundable, which can provide a greater deformation space for the side guard and meet the requirements for the vehicle to pass through relatively complex sections.

[0017] The following describes specific embodiments of the present utility model with reference to the drawings. In the following description, many specific details are set forth in order to enable those skilled in the art to more fully understand and implement the present utility model.

On the contrary, the present utility model can be implemented by any combination of the features and elements described below, regardless of whether they relate to different embodiments.

[0018] In Figures 1 - 3 a specific embodiment of the panel 1 of the side guard assembly for a vehicle through-passage of the present utility model is shown. The length direction of the panel 1 is Figure 1 the up-down direction in Figures 1 - 2 the figure. In the installed state of the panel 1, this length direction is consistent with the height direction of the vehicle. As shown in

[0019] Figure 2 Show Figure 1 A schematic cross-sectional view along line A-A of the panel shown, Figure 3 Also show Figure 2 An enlarged view of part Z in. The panel 1 includes a first plane 14 constituting one surface of the panel, a second plane 15 parallel to the first plane 14, two third planes 16 located on both sides of the second plane 15 in the width direction of the panel, and two inclined fourth planes 17 connecting the second plane 15 and the third planes 16 respectively. The distance between the first plane 14 and the second plane 15 in the thickness direction of the panel is a first thickness b, and the distance between the first plane 14 and the third plane 16 in the thickness direction is a second thickness a. These planes extend straight in the length direction of the panel 1. As can be seen from Figure 2 In, the panel 1 thus formed includes a central part 11 located at the central part of the panel 1 in the width direction of the panel, and two side parts 12 located on both sides of the central part 11 in the width direction of the panel. Among them, the central part 11 is flat and has the first thickness b, and the thicknesses of the two side parts 12 are both smaller than the first thickness b; the thicknesses of the two side parts 12 are preferably the same, which is the second thickness a, and the length of the two side parts 12 is c.

[0020] The panel 1 further includes two inclined transition parts 13, and each transition part 13 extends obliquely between the central part 11 and the corresponding side part 12 respectively. The sum of the lengths of each side part 12 and the corresponding transition part 13 is d. These first thickness b, second thickness a, length c and length d can be selected according to the actual requirements of the gangway and the vehicle. The thickness of the central part of the panel can ensure the strength requirements of the main contact surface with passengers to withstand the leaning or squeezing force of passengers. The smaller thicknesses of the side parts 12 and the transition parts 13 on both sides in the width direction of the panel are used to meet the requirements of panel winding and bending deformation to adapt to the relative movement between carriages. According to needs, the thickness of the central part 11 can also be set to be woundable.

[0021] It should be noted that although the panel 1 of the present invention is described as being wound as an example in this article, those skilled in the art can understand that due to the overall flat structure of the panel 1 of the present invention, it has the advantages described in this article, such as being easy to manufacture, low cost, improving force bearing and increasing service life, the relatively thick central part can withstand the force of passengers, the thinner parts on both sides are convenient for deformation to compensate for the movement between adjacent carriages, and avoiding the gaps and noises between panels in the multi-panel solution. These advantages do not depend on the winding type side guard movement mechanism to be realized. In other words, the panel 1 of the present invention can be used in other side guard movement mechanisms and also has the above advantages.

[0022] Those skilled in the art can make various modifications and variations to the embodiments disclosed above without departing from the scope or spirit of the present utility model. Based on the practice of the present utility model disclosed in this specification, other embodiments of the present utility model will be apparent to those skilled in the art.
