DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or embodiment. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or embodiments in a suitable manner.

[0029] The terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0030] In the accompanying drawings, the Z axis represents the vertical direction, that is, the up and down position, and the positive direction of the Z axis (that is, the direction of the arrow of the Z axis) represents the top, and the negative direction of the Z axis (that is, the direction opposite to the positive direction of the Z axis) represents the bottom; the X axis in the accompanying drawings represents the horizontal direction and is designated as the left and right position, and the positive direction of the X axis (that is, the direction of the arrow of the X axis) represents the right side, and the negative direction of the X axis (that is, the direction opposite to the positive direction of the X axis) represents the left side; the Y axis in the accompanying drawings represents the front and back position, and the positive direction of the Y axis (that is, the direction of the arrow of the Y axis) represents the front side, and the negative direction of the Y axis (that is, the direction opposite to the positive direction of the Y axis) represents the back side; it should be noted that the aforementioned Z axis, Y axis and X axis are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0031] In this specification, the content of the present invention will be described by taking the lower side beam of the suspended skyrail train as an example, but it is not limited thereto. Specifically, in the entire suspended skyrail, the Z positive direction may refer to the upper direction, the Y axis positive direction may be the forward direction of the vehicle body, and the X axis direction may be the width direction of the vehicle body.

[0032] like Figures 1 to 3As shown, an embodiment of the present invention provides a side beam, wherein the lower side beam comprises a beam body 1 and a first connecting structure 2, wherein the first connecting structure 2 is located above the beam body 1 and is integrally connected to the beam body 1, and a skirting structure 7 is provided on the first connecting structure 2.

[0033] It should be noted that the vehicle body generally includes two lower side beams, and the two lower side beams are symmetrically arranged about the center of the vehicle body width direction or the left and right direction (i.e., the X-axis direction). In this specification, one of the lower side beams located on the left side (i.e., opposite to the X-axis) will be used as an example to illustrate the contents of the present invention.

[0034] It should be noted that in traditional car bodies, skirtings are decorative lines set at the corners of side walls to prevent them from being damaged or dirty by feet. They can achieve better protection and visual balance effects. They are generally connected to the side walls by snap-on or other connection methods.

[0035] It should be noted that the beam body 1 and the skirting structure 7 are integrally connected, which can be welded, extruded, or machined. In addition, in this description, the first connection structure 2 is a hollow structure as an example to illustrate the content of the present invention. It can be made of multiple plates through bending, welding and other processes, or it can be extruded from aluminum alloy, which will not be described later.

[0036] The advantage of this arrangement is that, compared with the assembly method, there is no need to install a skirting board separately, which reduces the workload of vehicle assembly and can reduce the required installation space to a certain extent. In addition, the skirting board structure 7 is integrally connected to the beam body 1, which can enhance the rigidity of the lower side beam, and has high stability and reliability.

[0037] In the embodiment of the present invention, the first connection structure 2 is also used to connect with a side wall (not shown in the figure) of a vehicle body (not shown in the figure).

[0038] Exemplarily, the first connecting structure 2 includes a side wall connecting structure for connecting to the side wall. Along the width direction of the vehicle body, the skirting structure 7 is located on the side of the side wall connecting structure close to the center of the vehicle body. The specific structure of the connection between the side wall connecting structure and the side wall of the vehicle body is not limited. Exemplarily, a first plug interface is provided on the side wall connecting structure, and a second plug interface is provided at the lower end of the side wall. The first plug interface is plugged into the second plug interface to realize the positioning of the side wall connecting structure and the side wall connection (not shown in the figure), and then the side wall connecting structure and the side wall are welded together.

[0039] The advantage of this arrangement is that the first connecting structure is not only provided with a skirting structure 7, but can also be used to connect with the side wall, the rigidity and compressive performance of the lower side beam in the up and down direction and / or the width direction of the vehicle body can be reliably strengthened, and the structural stability and reliability are high.

[0040] like Figure 1 , Figure 2 and Figure 4 As shown, in the embodiment of the present invention, a receiving structure 25 is provided on the first connecting structure 2, and the receiving structure 25 is suitable for receiving the column 4 of the side wall.

[0041] like Figure 4 As shown, illustratively, the lower end of the column 4 is at least partially accommodated in the accommodation structure 25, and the accommodation structure 25 avoids the column 4 to avoid interference with the column 4. Exemplarily, the accommodation structure 25 includes an accommodation groove structure, and when the side wall is connected to the first connection structure 2, the lower end of the column 4 is at least partially accommodated in the accommodation groove structure.

[0042] The advantage of such an arrangement is that the lower end of the column 4 is at least partially accommodated in the accommodating structure 25, avoiding interference with the connection between the lower side beam and the side wall. The column 4 partially extends into the interior of the lower side beam, which can position the column 4 to a certain extent and enhance the stability and reliability of the connection between the lower side beam and the side wall.

[0043] like Figure 3 As shown, the first connection structure 2 is a hollow structure, and the first connection structure 2 includes a first outer shell structure 21 and a first intermediate connection structure 22 located inside the first outer shell structure 21 , and the first intermediate connection structure 22 is suitable for strengthening the first outer shell structure 21 .

[0044] like Figure 3 As shown, exemplarily, the first shell structure 21 includes a first plate 211, a second plate 212 and a third plate 213, the first plate 211 is located on the side of the second plate 212 and the third plate 213 close to the center of the vehicle body (that is, the side in the X-axis direction), the first plate 211 and the third plate 213 are arranged opposite to each other, the second plate 212 is sandwiched between the first plate 211 and the third plate 213, the upper ends of the first plate 211 and the third plate 213 are connected to the second plate 212, and the lower ends of the first plate 211 and the third plate 213 are connected to the beam body 1. At this time, the skirting structure 7 is arranged on the first plate 211, which will be described in detail later.

[0045] It should be noted that the first shell structure 21 can be a shell with a cavity formed separately and then connected to the beam body 1, or it can be connected to the beam body 1 and then share a side wall to form a cavity, that is, the first plate body 211, the second plate body 212, the third plate body 213 and part of the top plate 111 of the beam body 1 are combined to form a cavity of the first connection structure 2. In this case, a part of the top plate 111 of the beam body 1 serves as the bottom plate of the first connection structure 2.

[0046] Exemplarily, the first intermediate connection structure 22 divides the inner space of the first connection structure 2 into a plurality of compartments to enhance the stability of the first connection structure 2 .

[0047] The advantage of this arrangement is that the first connecting structure 2 is set as a hollow structure, and the internal support is strengthened by the first intermediate connecting structure 22, which can reduce the weight of the lower beam while ensuring the rigidity of the lower beam, improve the structural stability, and reduce the operating cost of the suspended sky rail.

[0048] like Figure 3 As shown, in an embodiment of the present invention, the first intermediate connecting structure 22 includes a first rib plate 221 extending in the up-down direction, and the side wall of the accommodating structure 25 away from the center in the width direction of the vehicle body (i.e., the side wall located in the positive direction of the X-axis) is connected to the first rib plate 221.

[0049] Exemplarily, the first intermediate connecting structure 22 includes ribs whose two ends are respectively connected to the two side walls of the first shell structure 21, for example, the upper end of the second rib 222 is connected to the third plate body 213 and the lower end thereof is connected to the top plate 111 of the beam body 1, the upper end of the third rib 223 is connected to the first plate body 211 and the lower end thereof is connected to the top plate 111 of the beam body 1, the upper end of the first rib 221 is connected to the second plate body 212, and the lower end of the first rib 221 is connected to the second rib 222 and / or the third rib 223 and / or the top plate 111. The two ribs of the first intermediate connecting structure 22 may also be connected to each other. For example, one end of the fourth rib 224 is connected to the connection between the second rib 222 and the third plate body 213, the other end of the fourth rib 224 is connected to the first rib 221, the upper end of the fifth rib 225 is connected to the connection between the first rib 221 and the second plate body 212, and the lower end of the fifth rib 225 is connected to the connection between the third rib 223 and the first plate body 211. This is not a limitation as long as it can strengthen the first connecting structure.

[0050] Exemplarily, along the width direction of the vehicle body, the inner surface of the side wall of the accommodating structure 25 away from the center of the width direction of the vehicle body (i.e., the surface located in the positive direction of the X-axis) is flush with or retracted inward from the surface of the first rib 221 close to the center of the width direction of the vehicle body (i.e., the surface located in the positive direction of the X-axis).

[0051] Here, it should be noted that the first rib plate 221 is not limited to being connected to the second plate body 212 at the upper end and the top plate 111 at the lower end, and it may also be indirectly connected to the second plate body 212 and / or the top plate 111 .

[0052] The advantage of such a configuration is that, by configuring the first rib 221 and connecting the side wall of the accommodating structure 25 away from the center in the width direction of the vehicle body to the first rib 221, it is possible to enhance the rigidity of the first connection structure 2 in the up and down directions while avoiding the collapse of the first connection structure 2 at the accommodating structure 2, thereby enhancing the structural stability of the periphery of the accommodating structure 25, and to increase the contact area between the side wall and the accommodating structure 25 to a certain extent, thereby achieving high reliability and stability in the connection between the lower side beam and the side wall.

[0053] like Figure 2 and Figure 4 As shown, in an embodiment of the present invention, the first connecting structure 2 is provided with a first positioning portion 251 and / or a second positioning portion 252 at the accommodating structure 25; the first positioning portion 251 is suitable for realizing the position positioning of the pillar 4 in the width direction of the vehicle body, and the second positioning portion 252 is suitable for realizing the position positioning of the pillar 4 in the length direction of the vehicle body.

[0054] like Figure 2 As shown, exemplarily, a first positioning portion 251 is provided on the side wall of the accommodating structure 25 along the width direction of the vehicle body, and / or a second positioning portion 252 is provided on the side wall of the accommodating structure 25 along the length direction of the vehicle body. Expectedly, both the first positioning portion 251 and the second positioning portion 252 include positioning surfaces.

[0055] like Figure 2 As shown, in some embodiments, the positioning surface of the first positioning portion 251 is flush with the inner surface of the side wall of the accommodating structure 25 away from the center in the width direction of the vehicle body. For example, the positioning surface of the first positioning portion 251 is the surface of the first rib plate 221 on the side close to the center in the width direction of the vehicle body. The first rib plate 221 contacts the column 4 to realize the position positioning of the column 4 in the width direction of the vehicle body.

[0056] In some embodiments, the positioning surface of the first positioning portion 251 protrudes from the inner surface of the side wall of the accommodating structure 25 away from the center in the width direction of the vehicle body (not shown in the figure). In this case, the first positioning portion 251 is a boss structure actually arranged on the side wall of the accommodating structure 25 away from the center in the width direction of the vehicle body. Here, the boss structure can be processed on the first rib plate 221, or it can be a pad welded on the first rib plate 221. In this way, at least part of the periphery of the boss structure can be welded to the column 4 to enhance the reliability of its connection. The setting of the second positioning portion 252 is similar to that of the first positioning portion 251, and will not be described in detail here.

[0057] The advantage of such a configuration is that the first positioning portion 251 and / or the second positioning portion 252 can realize the positioning of the pillar 4 in the width direction and / or the length direction of the vehicle body, the positioning is reliable, the connection positioning between the lower side beam and the side wall is reliable, and the practicability is strong.

[0058] Next, the present invention is described by taking the first rib plate 221 as the first positioning portion 251 and the first rib plate 221 being close to the center of the vehicle width direction to position the column 4 in the vehicle width direction as an example.

[0059] like Figure 3 As shown, in the embodiment of the present invention, along the width direction of the vehicle body, the upper end of the first rib plate 221 is adapted to be inclined toward a side away from the center of the vehicle body.

[0060] Exemplarily, the angle between the first rib plate 221 and the top plate 111 is 90°-120°, such as 95°, 97°, 100° or 110°. In this case, a corresponding angle should also be set on the bottom of the vehicle body side wall.

[0061] The advantage of such a configuration is that the upper end of the first rib 221 is inclined toward the side away from the center of the vehicle body, which can increase the left-right space in the middle part of the vehicle body (in the height direction) without changing the size of the bottom of the vehicle body, and the column 4 is subjected to an extrusion force toward the outside of the vehicle body, which has an outward extrusion tendency, reducing the possibility of the column 4 being squeezed toward the inside of the vehicle body, and the stability of the connection between the column 4 and the lower side beam is high.

[0062] like Figure 3 As shown, in an embodiment of the present invention, the beam body 1 is a hollow structure, the lower end of the first rib plate 221 extends to the top plate 111 of the beam body 1, the first rib plate 221 divides the cavity of the first connecting structure 2 into at least two compartments, and at least one of the combination of the two compartments of the first connecting structure 2 and the cavity of the beam body 1 is provided with a reinforcing rib plate, which is connected to the connection between the first rib plate 221 and the top plate 111.

[0063] like Figure 3 As shown, it should be noted that the beam body 1 is a hollow structure, which does not limit the specific structural shape and internal structure of the beam body 1. In some embodiments, the beam body 1 includes a second shell structure 11 enclosing at least one cavity, the second shell structure 11 and its cavity extend along the length direction of the vehicle body, and the two ends of the cavity along the length direction of the vehicle body are open. A plurality of reinforcing ribs or other structures may be provided inside the second shell structure 11 to divide the internal cavity of the second shell structure 11 into a plurality of cavities;

[0064] like Figure 3As shown, exemplarily, the second shell structure 11 includes a top plate 111, an outer plate 112, a bottom plate 113 and an inner plate 114 connected end to end in sequence, wherein the top plate 111 and the bottom plate 113 are arranged opposite to each other and the top plate 111 is located above the bottom plate 113, the outer plate 112 is a side plate on the second shell structure 11 away from the center of the vehicle body, and the inner plate 114 is a side plate on the second shell structure 11 close to the center of the vehicle body. The top plate 111, the outer plate 112, the bottom plate 113 and the inner plate 114 together form a polygonal prism-like structure with a cavity.

[0065] Here, one or more of the top plate 111, the outer plate 112, the bottom plate 113, and the inner plate 114 may be composed of a plurality of plates, for example, Figure 3 As shown, the inner panel 114 may include a first inner panel 1141 and a second inner panel 1142 connected to the lower end of the first inner panel 1141, and the upper end of the first inner panel 1141 is connected to the top panel 111; one or multiple adjacent ones of the top panel 111, the outer panel 112, the bottom panel 113 and the inner panel 114 may be set as an arc structure, for example, the outer panel 112 is set as an arc structure, the upper end of the outer panel 112 is connected to the lower end of the third plate body 213 of the first connecting structure 2, and the outer panel 112 is flush with the third plate body 213.

[0066] like Figure 3 As shown, exemplarily, the reinforcing rib plate includes a third rib plate 223 whose lower end is connected to the connection between the first rib plate 221 and the top plate 111, and the upper end of the third rib plate 223 is connected to the middle part of the first plate body 211 to support the first plate body 211; and / or, the reinforcing rib plate includes a second rib plate 222 whose lower end is connected to the connection between the first rib plate 221 and the top plate 111, and the upper end of the second rib plate 222 is connected to the middle and upper part of the third plate body 213; and / or, the reinforcing rib plate includes a sixth rib plate 131 whose upper end is connected to the connection between the first rib plate 221 and the top plate 111, and the lower end of the sixth rib plate 131 is connected to the outer plate 112, the first inner plate 1141 of the bottom plate 113 or the second inner plate 1142.

[0067] like Figure 3 As shown, in some embodiments, the beam body 1 includes at least one eighth rib 133 that is not connected to the first rib 221. Exemplarily, the eighth rib 133 divides the internal space of the second shell structure 11 into at least two cavities. At this time, the reinforcing rib may also include a seventh rib 132, the upper end of the seventh rib 132 is connected to the connection between the first rib 221 and the top plate 111, and the lower end of the seventh rib 132 is connected to the eighth rib 133. Exemplarily, at least one of the eighth ribs 133 is arranged horizontally, and the lower end of the seventh rib 132 is connected to the middle of the eighth rib 133.

[0068] It should be noted that the connection between the first rib plate 221 and the top plate 111 should be understood as an area rather than a point. For example, the width of the area can be 0-15 mm, 2-10 mm, or 3-6 mm.

[0069] The advantage of such a configuration is that, by providing a reinforcing rib, the first rib 221 and the top plate 111 can be supported in at least one direction, thereby enhancing the force-bearing performance of the first rib 221 and preventing the first rib 221 from collapsing along the width direction of the vehicle body during use. The structure has high stability and reliability, and the beam body 1 is a hollow structure, which can reduce the weight of the lower side beam, avoid excessive weight of the lower side beam, and reduce the cost of use.

[0070] like Figure 8 As shown, in an embodiment of the present invention, the reinforcing ribs further include at least one ninth rib 226, which is extended in the up-down direction, and the position of the ninth rib 226 is suitable for corresponding to the side wall position of the column 4 closer to the width direction of the vehicle body. Exemplarily, the ninth rib 226 is parallel to the first rib 221, and when the column 4 is accommodated in the accommodation structure 25, the ninth rib 226 is partially fitted with the column 4, and the ninth rib 226 is protruded from the column 4 along the width direction of the vehicle body toward the side close to the center of the vehicle body. In other words, along the length direction of the vehicle body, the projection of the ninth rib 226 on the column 4 is partially located within the area covered by the column 4, and partially located outside the area covered by the column 4, so that the contact between the column 4 and the ninth rib 226 forms an angle structure that is convenient for welding, and the reliability and stability of the welding are high.

[0071] In addition, in the accompanying drawings, the accommodating structure 25 is completely disposed through the skirting structure 7 along the width direction of the vehicle body, but this does not limit the present invention. Exemplarily, the accommodating structure 25 does not penetrate the skirting structure 7. Exemplarily, the accommodating structure 25 only penetrates a portion of the third surface structure 72 along the width direction of the vehicle body, which will not be described in detail here.

[0072] like Figure 3 and Figure 4 As shown, in the embodiment of the present invention, the first connection structure 2 further includes a second surface structure 23 located at the top, and the second surface structure 23 is suitable for realizing the position positioning of the side wall in the up and down directions.

[0073] Exemplarily, the second surface structure 23 is disposed on the second plate body 212 , and the position of the second surface structure 23 corresponds to the position of the accommodating structure 25 . The second surface structure 23 is suitable for realizing the position positioning of the column 4 in the up-down direction.

[0074] The advantage of such an arrangement is that the second surface structure 23 can reliably support the side wall, and the connection between the lower side beam and the side wall has high stability and reliability.

[0075] like Figure 3 and Figure 4 As shown, in the embodiment of the present invention, a first surface structure 5 is further included. The first surface structure 5 is arranged above the first connection structure 2. The first surface structure 5 is arranged at a first preset distance from the outer surface of the first connection structure 2 on the side away from the center in the width direction of the vehicle body. In other words, the first surface structure 5 is arranged at a first preset distance from the third plate 213. The first surface structure 5 is suitable for installing vehicle window glass (not shown in the figure). There are many ways to arrange the first surface structure 5. For example, it can be a plate-like structure or a hollow structure similar to the first connection structure 2, which will not be described in detail here.

[0076] Exemplarily, the first surface structure 5 is configured as a vertical plate structure, the outer side wall of which forms a partial mounting surface for mounting a vehicle window glass, and the outer surface of the vehicle window glass is flush or approximately flush with the outer side plate 112 of the beam body 1 .

[0077] like Figure 1 and Figure 4 As shown, exemplarily, two pillars 4 are provided on the side wall of the vehicle body corresponding to the window positions, and along the length direction of the vehicle body, the two pillars 4 are respectively located at the two ends of the window. In some embodiments, the outer side walls of the two pillars 4 are flush or approximately flush with the outer side plate 112 of the beam body 1, and flanges for installing the window glass are provided on the side walls of the two pillars 4 close to each other, and the outer side wall of the flange is flush or approximately flush with the vertical plate structure. When the window glass is installed, the inner surface of the window glass is fitted with the flange and the vertical plate structure, and the outer surface of the window glass is flush or approximately flush with the outer side walls of the two pillars 4 and the outer side plate 112 of the beam body 1.

[0078] like Figure 1 , Figure 5 and Figure 6 As shown, exemplarily, three pillars 4 are arranged on the side wall of the vehicle body corresponding to the window positions. For example, the pillar 4 located in the middle is the middle pillar 41, and the outer wall of the middle pillar 41 is flush or approximately flush with the outer wall of the vertical plate structure. When the window glass is installed, the inner surface of the window glass is fitted with the outer wall of the middle pillar 41 and the vertical plate structure, and the outer surface of the window glass is flush or approximately flush with the outer walls of the two pillars 4 and the outer plate 112 of the beam body 1.

[0079] The advantage of this arrangement is that the first surface structure 5 can realize the positioning of the vehicle window glass. The first surface structure 5 is arranged above the first connecting structure 2, so that the vehicle window glass can obtain a larger coverage area, and the first connecting structure 2 can support the vehicle window glass, thereby facilitating the installation of the vehicle window glass.

[0080] In an embodiment of the present invention, along the length direction of the vehicle body, the first surface structure 5 is at least partially sandwiched between two pillars 4 corresponding to the vehicle windows (not shown in the figure) to achieve the position positioning of the pillars 4 corresponding to the vehicle windows in the length direction of the vehicle body.

[0081] That is to say, along the width direction of the vehicle body, the first surface structure 5 is at least partially retracted into the outer wall of the pillar 4. According to actual needs, the first surface structure 5 can be set to a plate-like structure or a hollow structure. Along the width direction of the vehicle body, the plate-like structure or the hollow structure can be set to a step-like structure, which will not be described in detail here.

[0082] The advantage of such an arrangement is that, during the assembly (welding) process, the first plate body 211 is used to position the column 4 corresponding to the window in the left-right direction (i.e., the width direction of the vehicle body), the second plate body 212 is used to position the column 4 in the up-down direction, and the first surface structure 5 is used to position the column 4 in the length direction of the vehicle body. The column 4 and the lower side beam are reliably positioned in three-dimensional space, have reliable positioning, a large contact area, and high force (welding) stability.

[0083] like Figure 3 As shown, in an embodiment of the present invention, the skirting structure 7 includes a curved surface structure 71, which is arranged on the side wall of the first connecting structure 2 close to the center of the width direction of the vehicle body, and the curvature center axis of the curved surface structure 71 extends along the length direction of the beam body 1, and the curvature center axis is located on the side of the curved surface structure 71 close to the center of the width direction of the vehicle body, and the lower end of the curved surface structure 71 extends to the beam body 1 and is connected to the beam body 1.

[0084] Exemplarily, the curved surface structure 71 is arranged on the first plate 211, and along the width direction of the vehicle body, the lower end of the curved surface structure 71 is flush with the side wall (or the pillar 4), or the lower end of the curved surface structure 71 is arranged to protrude from the side wall (or the pillar 4) toward the side close to the center of the width direction of the vehicle body.

[0085] Exemplarily, both upper and lower ends of the arc surface structure 71 are arranged to protrude from the side wall (or the pillar 4 ) toward a side close to the center in the width direction of the vehicle body.

[0086] The advantage of such a setting is that the skirting structure 7 includes a curved surface structure 71, through which a smooth transition between the first connecting structure 2 and the beam body 1 is achieved, and the connection has high stability, which avoids stress concentration, and the curved surface structure 71 makes it difficult for dust or foreign matter to accumulate on the upper beam, thereby facilitating cleaning. At the same time, the setting of the curved surface makes it easy to fit the floor cloth with the curved surface structure when laying the floor cloth, without any gap, and the floor cloth can be laid to a preset height position on the curved surface structure 71 according to actual needs, without the need for a separate skirting structure, and the structure is reliable and stable.

[0087] In some embodiments, the first plate 211 is an overall curved structure (not shown in the figure), such as Figure 3 As shown, in other embodiments, the lower portion of the first plate body 211 is a curved surface structure 71, and the upper portion of the first plate body 211 is a third surface structure 72. The lower end of the third surface structure 72 is connected to the curved surface structure 71, for example, tangent to it. That is to say, the skirting structure 7 includes the third surface structure 72, and the baseboard cloth can be laid on the third surface structure 72, for example, laid on the second plate body 212, which will not be described in detail here.

[0088] like Figure 3 As shown, in an embodiment of the present invention, a mounting groove structure 6 is further included, the beam body 1 is hollow, and a groove cavity 61 of the mounting groove structure 6 is at least partially located inside the second shell structure 11 .

[0089] Exemplarily, the mounting slot structure 6 includes a T-slot structure, and along the depth direction of the T-slot, the bottom wall of the T-slot structure is retracted into the outer surface of the second shell structure 11 .

[0090] like Figure 3 As shown, it should be noted that the position and number of the mounting groove structure 6 are set according to actual needs. For example, at least one mounting groove structure 6 is respectively arranged at at least one of the bottom plate 113, the inner plate 114 and the top plate 111. The mounting groove structure 6 arranged corresponding to the top plate 111 can be used to install accessories such as floors, and the mounting groove structure 6 arranged corresponding to the bottom plate 113 and / or the inner plate 114 can be used to install accessories such as bottom sealing plates. In this specification, the mounting groove structure 6 arranged corresponding to the bottom plate 113 will be taken as an example to illustrate the contents of the present invention, but it is not limited to this.

[0091] Next, the manner in which the mounting groove structure 6 is connected to accessories such as a bottom sealing plate is exemplified: when accessories such as a bottom sealing plate need to be installed, the position of the accessories such as the bottom sealing plate is aligned with the position of the mounting groove structure 6, and the position of the mounting groove structure 6 and the accessories such as the bottom sealing plate are connected by various connection methods, for example, the mounting groove structure 6 and the accessories such as the bottom sealing plate are connected by screws; the mounting groove structure 6 can realize the positioning and / or installation of accessories such as the bottom sealing plate. In some embodiments, when the mounting groove structure 6 includes a T-slot structure, the end of the T-bolt where the T-structure is located can be placed into the T-slot structure, and then the mounting hole on the accessories such as the bottom sealing plate is passed through the T-bolt, and then the accessories such as the bottom sealing plate are pressed against the lower side beam by a nut threadedly connected to the T-bolt or a component with a nut.

[0092] The advantage of such a configuration is that the groove cavity 61 of the mounting groove structure 6 is at least partially located inside the beam body 1, which can reduce the space occupied by the lower side beam and make the structure of the lower side beam more compact. While facilitating the installation of accessories connected to the lower side beam (such as the bottom sealing plate), it can enhance the structural rigidity of the beam body 1 and the mounting groove structure 6 to a certain extent, thereby preventing the mounting groove structure 6 on the upper side beam from being damaged or failing due to excessive local force, thereby affecting its service life. The lower side beam has high stability and reliability and is highly practical.

[0093] like Figure 3 As shown, in the embodiment of the present invention, a second intermediate connection structure 15 located inside the beam body 1 is further included, and the second intermediate connection structure 15 is connected to the mounting groove structure 6 and the beam body 1 respectively.

[0094] like Figure 3 As shown, the specific structure of the second intermediate connection structure 15 is not limited, and it only needs to be able to realize the connection between the beam body 1 and the mounting groove structure 6. Exemplarily, the second intermediate connection structure 15 includes a first connection plate 151, and the first connection plate 151 is connected to the side wall of the mounting groove structure 6, and at least one end of the first connection plate 151 is connected to the second shell structure 11.

[0095] The advantage of such a setting is that the second intermediate connecting structure 15 provides more connecting supports between the beam body 1 and the mounting groove structure 6, thereby enhancing the stability and reliability of the connection between the beam body 1 and the mounting groove structure 6, avoiding deformation of the beam body 1 at the opening of the mounting groove structure 6, and making the structure of the lower side beam more reliable, with high stability and reliability.

[0096] like Figure 3 As shown, in an embodiment of the present invention, the second intermediate connecting structure 15 includes a first connecting plate 151 and a second connecting plate 152, the first connecting plate 151 is respectively connected to the mounting groove structure 6 and the beam body 1, and the second connecting plate 152 is connected to at least two of the mounting groove structure 6, the beam body 1 and the first connecting plate 151.

[0097] like Figure 7 As shown, in the present specification, the content of the present invention will be explained by taking the installation groove structure 6 corresponding to the position of the bottom plate 113 and the groove of the installation groove structure 6 facing downward as an example. Specifically, along the width direction of the vehicle body (that is, the X-axis direction), the side wall on the installation groove structure 6 located on the outside (and in the opposite direction of the X-axis in the accompanying drawings) is the first side wall 62, and the side wall on the installation groove structure 6 located on the inside is the second side wall 63. In other words, the second side wall 63 is the side wall on the installation groove structure 6 that is arranged opposite to the first side wall 62, and the side wall on the installation groove structure 6 that is connected between the first side wall 62 and the second side wall 63 is the third side wall 64. In other words, the third side wall 64 is the bottom wall of the installation groove structure, which is arranged opposite to the groove of the installation groove structure 6 and will not be described in detail later.

[0098] like Figure 7 As shown, in some embodiments, the first connecting plate 151 is connected to the first side wall 62 of the mounting slot structure 6, the lower end of the first connecting plate 151 is connected to the bottom plate 113 of the second shell structure 11, the second connecting plate 152 is connected to the second side wall 63 of the second shell structure 11, and the lower end of the second connecting plate 152 is connected to the bottom plate 113 of the second shell structure 11.

[0099] In some embodiments, the two ends of the second connecting plate 152 are respectively connected to the first connecting plate 151 and the first side wall 62 (not shown in the figure). At this time, in some embodiments, the second connecting plate 152 can also extend toward one end away from the first side wall 62 at the connection with the first connecting plate 151 to connect to the second shell structure 11.

[0100] The advantage of such a configuration is that the first connecting plate 151 and the second connecting plate 152 provide the mounting groove structure 6 with multiple force supports, which greatly enhances the force stability of the mounting groove structure 6 and can enhance the force stability of the lower side beam to a certain extent, with high reliability and safety.

[0101] like Figure 7 As shown, in an embodiment of the present invention, the second connecting plate 152 is respectively connected to the beam body 1 and the first connecting plate 151, and a first accommodating cavity for accommodating the mounting groove structure 6 is formed between the second connecting plate 152 and the first connecting plate 151, and the mounting groove structure 6 is respectively connected to the first connecting plate 151 and the second connecting plate 152.

[0102] like Figure 7 As shown, exemplarily, the upper end of the first connecting plate 151 is connected to the upper end of the second connecting plate 152, and the lower ends of the first connecting plate 151 and the second connecting plate 152 are respectively connected to the bottom plate 113 of the second shell structure 11, and the angle between the first connecting plate 151 and the second connecting plate 152 is less than 180 degrees, and the opening formed by the angle faces downward, along the width direction of the vehicle body, and the third side wall 64 is sandwiched between the first connecting plate 151 and the second connecting plate 152, and the first connecting plate 151 and the second connecting plate 152 are respectively connected to the two ends of the third side wall 64 to form a reliable support for the mounting groove structure 6, as shown in FIG. Figure 2 As shown, at this time, the first connecting plate 151 can also overlap with the first side wall 62.

[0103] like Figure 2As shown, it should be noted that the second intermediate connecting structure 15 may also include other structures. In some embodiments, the first connecting plate 151 and / or the second connecting plate 152 may also be respectively provided with connecting plates for connecting the mounting slot structure 6 and / or the beam body 1. Exemplarily, at least one third connecting plate 153 is connected at the connection between the first connecting plate 151 and the second connecting plate 152, and the plurality of third connecting plates 153 are respectively connected to different positions of the second outer shell structure 11, so that the mounting slot structure 6 is connected to the second outer shell structure 11 as a whole, supports the second outer shell structure 11 from the inside, and enhances the stability of the mounting slot structure 6 and the second outer shell structure 11.

[0104] The advantage of this arrangement is that inside the beam body 1, the mounting groove structure 6 has a plurality of force supports, and the plurality of force supports are connected as a whole, so that the force stability of the mounting groove structure 6 is greatly enhanced. At the same time, the structure of the beam body 1 is also enhanced, and the stability and reliability of the lower side beam are high.

[0105] In an embodiment of the present invention, the beam body 1 and the mounting groove structure 6 are both extended along the length direction of the vehicle body, and at least one of the side of the beam body 1 close to the middle beam 8 of the chassis, the side close to the floor, and the bottom is provided with a mounting groove structure 6, and the groove of the mounting groove structure 6 is flush with the outer surface of the beam body 1.

[0106] like Figure 7 As shown, in some embodiments, a mounting groove structure 6 is provided at the bottom plate 113, and the mounting groove structure 6 is used to install accessories such as a bottom sealing plate. Along the depth direction of the mounting groove structure 6, the notch of the mounting groove structure 6 is flush with the outer surface of the bottom plate 113 or slightly retracted from the outer surface of the bottom plate 113. Exemplarily, the distance between the notch of the mounting groove structure 6 and the outer surface of the bottom plate 113 is 0-10 mm, for example, 6-8 mm. Figure 1 As shown, a mounting groove structure 6 is provided on one side of the beam body 1 close to the middle beam 8 of the chassis, on one side close to the floor, and in the bottom plate 113 .

[0107] It should be noted that, along the length direction of the vehicle body, an opening structure can be provided on the beam body 1 for facilitating the removal of components such as T-bolts or the placement of components into the installation groove structure 6. The opening structure extends along the width direction of the vehicle body to avoid the need for T-bolts and other accessories to be removed or placed into the installation groove structure 6 by sliding a long distance. This will not be described in detail here.

[0108] The advantage of this arrangement is that it can provide installation interfaces for accessories such as bottom cover plates and floors, making installation quick and easy. At the same time, the notch of the installation slot structure 6 is flush with the outer surface of the beam body 1, so that the lower side beam can be placed at any angle without causing damage to the installation slot structure 6, and has high safety and reliability.

[0109] For example, during the assembly of the lower side beam and the body side wall, the body side wall is abutted against the first rib plate 221 to realize the position of the body side wall in the left-right direction, and the body side wall is abutted against the second plate 212 to realize the position of the body side wall in the up-down direction, and then the body side wall and the lower side beam are connected together by various connection methods such as welding. At this time, in some embodiments, the bottom end of the body side wall is set at a distance from the top plate 111, and the space between the two can be used to install other structures; in some embodiments, the bottom end of the body side wall directly contacts the top plate 111, and its contact surface is larger and the connection is more stable.

[0110] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in an embodiment of the present invention, a second connecting structure 3 for connecting to the middle beam 8 of the chassis is also included. The second connecting structure 3 includes an upper plate 31. The upper plate 31 is set at a second preset distance from the top plate 111 of the beam body 1. The upper surface of the upper plate 31 is suitable for fitting with the middle beam 8 of the chassis. When the lower side beam is in a state of fitting with the middle beam 8 of the chassis, the top plate 111 is flush with the middle beam 8 of the chassis, and the connection between the lower side beam and the middle beam 8 of the chassis is achieved by welding or the like.

[0111] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the second connection structure 3 further includes a lower plate 32, which is located below the upper plate 31, and the lower plate 32 is suitable for connecting with the chassis middle beam 8. Exemplarily, the upper surface and / or the lower surface of the lower plate 32 are respectively in contact with the chassis middle beam 8. At this time, optionally, the upper surface of the lower plate 32 is in contact with the chassis middle beam 8, and the lower surface of the lower plate 32 is flush with the bottom surface of the chassis middle beam 8. In addition, the lower plate 32 and the chassis middle beam 8 can also be connected by a plug-in connection structure, which will not be described in detail here.

[0112] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it should be noted that a structure compatible with the second connecting structure 3 should be set on the middle beam 8 of the chassis. For example, a plate-like structure that fits the upper plate 31 is set on the middle beam 8 of the chassis. The thickness of the plate-like structure is equal to the second preset distance. When the structure of the second connecting structure 3 changes, the middle beam 8 of the chassis changes accordingly, which will not be described in detail here.

[0113] The advantage of such a configuration is that the upper plate 31 can support the middle beam 8 of the chassis from below, and to a certain extent can achieve the flushness of the top plate 111 of the beam body 1 and the middle beam 8 of the chassis. The connection between the lower side beam and the middle beam 8 of the chassis is achieved through the upper plate 31 and the lower plate 32. The contact area between the upper side beam and the middle beam 8 of the chassis is large, and the connection (welding) structure is reliable, highly stable, and highly practical.

[0114] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in the embodiment of the present invention, the second connection structure 3 further includes a third intermediate connection structure 33, and the third intermediate connection structure 33 is respectively connected to at least two of the upper plate 31, the lower plate 32 and the beam body 1. The third intermediate connection structure 33 may be arranged in a manner similar to the first intermediate connection structure 22, and will not be described in detail here.

[0115] The advantage of such a configuration is that the overall structural rigidity of the third intermediate connection structure 33 can be enhanced as a whole, so that the connection between the lower side beam and the chassis intermediate beam 8 is more stable and has high reliability.

[0116] like Figure 7 As shown, in some embodiments, the third intermediate connecting structure 33 includes an intermediate plate 331, the upper end of the intermediate plate 331 is inclined toward the side close to the beam body 1; the upper end of the intermediate plate 331 is connected to the upper plate 31, and / or the lower end of the intermediate plate 331 is connected to the lower plate 32; and the projection of one end of the upper plate 31 away from the beam body 1 on the lower plate 32 is located in the area covered by the projection of the intermediate plate 331 on the lower plate 32, and the projection of the intermediate plate 331 on the lower plate 32 is located in the area covered by the upper surface of the lower plate 32.

[0117] Exemplarily, along the width direction of the vehicle body, the end of the lower plate 32 away from the beam body 1 is arranged beyond the upper plate 31, the upper end of the middle plate 331 is connected to the end face of the upper plate 31 away from the beam body 1, and the lower end of the middle plate 331 is connected to the portion of the lower plate 32 that exceeds the upper plate 31. That is to say, along the width direction of the vehicle body, the entire middle plate 331 and the portion of the lower plate 32 away from the beam body 1 both exceed the upper plate 31.

[0118] The advantage of such a configuration is that the middle plate 331 can not only enhance the structural stability of the third middle connecting structure 33, but also the middle plate 331, the upper plate 31 and the lower plate 32 can all support the chassis middle beam 8 from below to a certain extent, thereby enhancing the stability of the connection between the lower side beam and the chassis middle beam 8.

[0119] In an embodiment of the present invention, the lower side beam extends along the length direction of the vehicle body, and part or all of the lower side beam is integrally extruded.

[0120] like Figure 6 As shown, in some embodiments, along the length direction of the vehicle body, the lower side beam includes a first section 101 corresponding to the window near the head of the vehicle body, a second section 102 corresponding to the door body near the head of the vehicle body, a third section 103 corresponding to the window in the middle of the vehicle body, a fourth section 104 corresponding to the door body far from the head of the vehicle body, and a fifth section 105 corresponding to the window far from the head of the vehicle body. After the lower side beam is integrally extruded, it is processed to form a structure in which the first section 101, the second section 102, the third section 103, the fourth section 104 and the fifth section 105 are connected in sequence, the second section 102 and the fourth section 104 are arranged corresponding to the door body, the first section 101, the third section 103 and the fifth section 105 are arranged corresponding to the window, the first section 101, the third section 103 and the fifth section 105 are all arranged with a first connection structure 2, the first surface structure 5 is arranged on the first connection structure 2 corresponding to the installation position of the window glass, and the accommodating structure 25 is arranged corresponding to the installation position of the pillar 4.

[0121] Exemplarily, the beam body 1, the first connecting structure 2, the first surface structure 5 and the second connecting structure 3 are extruded as a whole, and then the first section 101, the second section 102, the third section 103, the fourth section 104 and the fifth section 105 are obtained by processing; exemplarily, the first section 101, the second section 102, the third section 103, the fourth section 104 and the fifth section 105 are respectively processed as a whole and then connected as a whole.

[0122] The advantage of such an arrangement is that the weight of the lower plate edge is reduced, and its structural stability can be maintained, with high reliability and strong practicality.

[0123] Another embodiment of the present invention provides a suspended skyrail train, comprising any of the above-mentioned lower side beams. The suspended skyrail train has all the beneficial effects of the lower side beam, which will not be described in detail here.
