Description

Technical Field

[0001] The present invention relates to a vehicle having multiple carriages. Specifically, the present invention relates to an aisle connection connecting adjacent carriages and the side walls of the aisle connection. Background Art

[0002] Rail vehicles such as subways usually have two or more carriages. An aisle connection is usually provided between two adjacent carriages to enable people to move between the two carriages. The side wall is part of the aisle connection, installed on the side, and together with the pedal and the top plate, forms a passage between the carriages and serves to protect passengers.

[0003] As the vehicle passes through various road conditions such as turning during actual operation, the side wall will undergo single or combined movements such as rotation, stretching or compression, excessive height, roll, and nodding, and the movement form is complex. In order to adapt to the complex movement mode, a three-piece side wall is a common form of side wall. The existing three-piece side wall includes a middle wall panel, a left wall panel, a right wall panel, and at least two sets of link mechanisms composed of four short rods and two long rods. The two ends of the long and short links are hinged to each other. After the ends of the short links are hinged, they are respectively connected to the left wall panel and the right wall panel. The middle parts of the two long rods are hinged and connected to the middle wall panel. The connection points between the links and the wall panels need to be designed with free rotation. The two sets of four-link mechanisms are respectively installed at the upper and lower parts of the middle wall panel, the left wall panel, and the right wall panel.

[0004] However, in the existing three-piece side wall, during the operation of the vehicle, due to the complex movement form of the side wall, a large gap will be generated between the middle wall panel and the left wall panel or the right wall panel, posing a risk of pinching passengers and affecting aesthetics.

[0005] Furthermore, since the middle wall panel, the left wall panel, and the right wall panel are often made of hollow aluminum profiles and have a large stiffness in the thickness direction, while the links are made of thin plates and have a small stiffness in the thickness direction. During vehicle operation, for example, when the vehicle body rolls, due to the large stiffness of the wall panels and the small stiffness of the links, the links will be forced to deform to adapt to the vehicle curve requirements, resulting in contact between the middle wall panel and the left wall panel or the right wall panel at one of the upper and lower ends with a large stress, and a gap appears at one end, posing a risk of pinching passengers.

[0006] In addition, in the existing design, wear strips such as plastic wear strips are installed on the middle side wall panel to rub against the left and right wall panels, and the frictional force will increase during roll. In this case, scratches and stains will quickly appear on the surfaces of the left and right wall panels. Especially after a long time of operation, the surface states of the left and right wall panels are very poor. Moreover, noise will occasionally occur when the wear strips move on the left and right wall panels, affecting passenger comfort.

[0007] Therefore, the object of the present invention aims to solve at least one aspect of the above problems and requirements existing in the prior art and / or other technical problems. Summary of the Invention

[0032] The technical solutions of the present invention will be further specifically described below through embodiments in combination with the accompanying drawings. The description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the general concept of the present invention and should not be construed as a limitation to the present invention.

[0033] In addition, in the following detailed description, for the sake of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments. However, it is obvious that one or more embodiments can also be implemented without these specific details. In other cases, well-known structures and devices are not shown in a diagrammatic manner to simplify the drawings.

[0034] Figure 1 A schematic plan view of the side wall is shown, which is a view observed from the outside of the car body towards the inside of the car body to more clearly show the composition of the side wall, the arrangement of the link mechanism, and the position of the gap covering member.

[0035] As Figure 1 、 3 、4 shown, and in combination with Figure 6 the schematic principle diagram shown, as an exemplary first embodiment of the present invention, a side wall for a gangway of a vehicle is provided. The side wall includes an intermediate portion 1 and two side portions 2 provided on both sides of the intermediate portion 1. The intermediate portion 1 includes a single-layer plate 11; each of the two side portions 2 includes a first plate 21 facing the inside of the vehicle and a second plate 22 located on the side of the first plate 21 close to the outside of the vehicle. Both ends of the single-layer plate 11 are respectively clamped between the corresponding first plate 21 and second plate 22 and can move relative to the corresponding first plate 21 and second plate 22.

[0036] With this structure, since both ends of the single-layer plate 11 are respectively clamped between the corresponding first plate 21 and second plate 22 and can move relative to the corresponding first plate 21 and second plate 22, while ensuring the relative movement between the single-layer plate and the first and second plates during the operation of the vehicle and completing the complex movement of the side wall, the gap between the single-layer plate and the double-layer plate is avoided, and the risk of pinching passengers caused by the gap is reduced or even eliminated.

[0037] In the above example, a structural form of a side wall is described, in which a structure of clamping a middle single-layer wall plate by double-layer wall plates at both ends is adopted. However, those skilled in the art can understand that other forms can also be adopted, such as Figure 7Schematic diagram of the composition principle of the side wall according to the second exemplary embodiment of the present invention. The side wall for the gangway of a vehicle includes an intermediate portion 1' and two side portions 2' provided on both sides of the intermediate portion 1'; wherein, the intermediate portion 1' includes a first plate 11' facing the interior of the vehicle and a second plate 12' located on the side of the first plate 11' close to the outside of the vehicle; the two side portions 2' respectively include single-layer plates 21', and one end of each single-layer plate 21' close to the intermediate portion 1' is clamped between the corresponding first plate 11' and second plate 12' and can move relative to the corresponding first plate 11' and second plate 12'. In this example, the structure of clamping single-layer walls on both sides by an intermediate double-layer wall panel is adopted, and it can also achieve the effect of avoiding the gap between the single-layer plate and the double-layer plate and reducing or even eliminating the risk of pinching passengers caused by the gap.

[0038] The examples described below are described by taking the first embodiment as an example. However, it should be noted that its structure, function and effect are also applicable to the second embodiment described above, and for the sake of simplicity, they will not be described item by item again.

[0039] As an example, as Figure 1 , 2 shown, the side wall further includes at least two sets of link mechanisms 3 spaced apart in the height direction of the vehicle, and each set of link mechanisms 3 includes four first rods 31 (the shorter rods shown in the figure) and two second rods 32 (the longer rods shown in the figure). The two ends of the second rod 32 are respectively hinged to one first rod 31, and the two second rods 32 are hinged at their approximate middle positions and connected to the single-layer plate 11. The two adjacent first rods on both sides are hinged and connected to the second plate 22.

[0040] Correspondingly, for the structure of the second embodiment, the two second rods are hinged at their approximate middle positions and connected to the second plate of the intermediate portion, and the two adjacent first rods are hinged and connected to the single-layer plate of the side portion.

[0041] Through the above link mechanism, the support of the intermediate portion and the desired relative movement are achieved, and at least two sets of link mechanisms make the movement and deformation of the side wall more balanced throughout the height of the vehicle.

[0042] As an example, both the first rod 31 and the second rod 32 of the link mechanism are profiles. Preferably, the link mechanism adopts aluminum profiles. Since the stiffness in the thickness direction of the hollow profile is relatively large, the stiffness of the link mechanism in the thickness direction is relatively large, avoiding large deformation of the link mechanism when the vehicle rolls sideways. Those skilled in the art can understand that both aluminum and aluminum profiles are known materials and known structures. Applying aluminum profiles to the link mechanism with a shape structure here does not belong to an improvement made to the material itself.

[0043] As an example, the single-layer board 11, the first board 21, and the second board 22 are all made of aluminum alloy plates. Those skilled in the art can understand that aluminum alloy is a known material. Applying aluminum alloy to the single-layer board 11, the first board 21, and the second board 22 with shapes and structures does not belong to an improvement to the material itself. In this solution, a connecting rod structure composed of a thin aluminum alloy plate with a smaller stiffness and an aluminum profile with a larger stiffness is used. When the vehicle rolls over, the connecting rod mechanism has a larger stiffness and can drive the thin aluminum alloy plate to move with it. At the same time, the clamping force of the double-layer board can effectively clamp the single-layer intermediate board, avoiding gaps between the single-layer board and the first board or the second board.

[0044] As an example, the side wall further includes flannel 5 respectively arranged on opposite sides of the first board 21 and the second board 22. Flannel refers to a cotton fabric with a plump and fluffy surface. Those skilled in the art can understand that flannel is a known material. Applying flannel to the first board 21 and the second board 22 with shapes and structures does not belong to an improvement to the material itself. The setting of the flannel can reduce the friction between the single-layer board and the first board and the second board, making their relative movement smoother, effectively avoiding the wear of the single-layer board, protecting the painted surface of the single-layer board, and reducing the noise generated by friction, improving the passenger riding experience.

[0045] As Figure 3 , 4 shown, as an example, the first board 21 and the second board 22 are connected by fasteners 6 on the side away from the single-layer board 11 to maintain the clamping force on the single-layer board 11 therebetween. This structure ensures the clamping force on the single-layer board to prevent it from slipping out between the double-layer boards during their relative movement. In Figure 4 shown, the fastener 6 also passes through the bracket 9, and the bracket 9 is used to connect the connecting rod mechanism to the second board 22.

[0046] Preferably, in order to further ensure the clamping force on the single-layer board 11, a bending portion 221 can be formed on the second board 22. As Figure 4 shown, the bending portion extends obliquely towards the first board 21, thereby defining a gradually decreasing gap between the first board 21 and the second board 22 in the direction towards the single-layer board. Exemplarily, the second board 22 can be bent, for example, at the line L-L. The bending angle can be, for example, 1-5 degrees, preferably 2 degrees.

[0047] Preferably, the first board 21 includes a hollow boss 211 protruding towards the second board 22 and a connecting block 41 arranged in the hollow boss 211, wherein the second board 22 abuts against the hollow boss 211 and is connected to the first board 21 by connecting the fastener to the connecting block 41.

[0048] The connecting block 41 may be provided with threaded holes to function as nuts, and the first plate 21 and the second plate 22 are connected by screwing a fastener 6 into the threaded holes. Through the arrangement of the above-mentioned hollow boss 211 and the connecting block 41 therein, the connection between the first plate and the second plate can be achieved without the fastener being exposed inside the vehicle. As an example, both the hollow boss and the connecting block 41 therein extend along the height of the first plate, and at the end, space is left for the installation of the covering member and they do not extend flush with the first plate 21, as Figure 5 shown.

[0049] The side wall is pivotally connected to the body end wall of the two-layer carriage through a mounting bracket 7 as a whole. Exemplarily, in order to reduce the friction between the first plate and the body end wall, as Figures 3 - 5 shown, the first plate 21 is formed with an arc portion 212 at one end away from the single-layer plate 11.

[0050] In order to cover the gaps between the side wall of the through passage and the top plate and the bottom pedal of the through passage respectively, covering members are also provided in the middle portion and the two side portions respectively. Specifically, the middle portion 1 further includes two first covering members 12 respectively connected to the upper and lower ends of the single-layer plate 11, for covering the gaps between the single-layer plate 11 and the top plate of the through passage and between the single-layer plate 11 and the pedal of the through passage respectively; and each of the two side portions 2 includes two second covering members 23 respectively connected to the upper and lower ends of the first plate 21, for covering the gaps between the first plate 21 and the top plate of the through passage and between the first plate 21 and the pedal of the through passage respectively; there is a gap between the first covering member 12 and the second covering member 23 in the lateral direction of the vehicle (i.e., in the direction substantially perpendicular to the plate plane of the single-layer plate and / or the first plate and the second plate).

[0051] Through the arrangement of the middle portion 1 and the side portions 2 including the first covering member and the second covering member with the above structure, the gaps between the side wall and the top plate and the bottom pedal are avoided, the risk of passengers being pinched is reduced, and the aesthetics inside the carriage are improved. The gap between the first covering member 12 and the second covering member 12 avoids their interference.

[0052] Furthermore, in order to form a gap between the first covering member 12 and the second covering member 23, as Figure 3 shown, the first covering member 12 may be arranged on the side of the single-layer plate 11 facing the outside of the vehicle body (shown as the upper side of the single-layer plate 11 in Figure 3 ), and the second covering member 23 is arranged on the side of the first plate 21 facing the inside of the vehicle body (shown as the upper and lower sides of the first plate 21 in Figure 3 ). For this purpose, as Figure 1 , 2 shown, the height of the second plate 22 in the vehicle height direction is less than the height of the single-layer plate 11 to avoid interference between the covering member and the second plate 22.

[0053] The present invention also relates to an accordion-type passageway, which includes the side walls of the above respective examples. The accordion-type passageway thus has the advantages of the side walls of the above respective structures.

[0054] The present invention also relates to a vehicle including at least two carriages, and the vehicle includes the accordion-type passageway as described above disposed between two adjacent carriages. The vehicle thus has the advantages of the side walls and the accordion-type passageway of the above structure. Those skilled in the art can understand that the vehicle can be any vehicle including carriages that need to be connected, such as a subway, a train, a bus, etc.

[0055] Although some embodiments of the general concept of the present invention have been shown and described, those of ordinary skill in the art will understand that changes can be made to these embodiments without departing from the principles and spirit of the general concept of the present invention, and the scope of the present invention is defined by the claims and their equivalents.
