DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The core of the utility model is to provide a rail vehicle body, which can effectively improve the stability of the vehicle body by plugging and connecting a side wall body with an upper side beam body.

[0033] Another core of the utility model is to provide a rail vehicle comprising the rail vehicle body.

[0034] This specific embodiment discloses a rail vehicle body, including a side wall body 2 and an upper side beam body 1 . The upper side beam body 1 is provided with a groove 11 for installing the side wall body 2 . The side wall body 2 is inserted into the groove 11 .

[0035] like Figure 1 As shown, the side wall body 2 is inserted into the groove 11 of the upper side beam body 1, and combined with Figure 3 , Figure 4 It can be seen that the portion of the side wall body 2 inserted into the groove 11 is a hollow structure, one side wall of the side wall body 2 fits with one side wall of the groove 11 , and the other side wall of the side wall body 2 fits with the other side wall of the groove 11 .

[0036] In the rail vehicle body provided in this specific embodiment, the side wall body 2 is inserted into the groove 11 of the upper side beam body 1. Compared with the existing connection method, the plug-in connection method can make the connection between the side wall body 2 and the upper side beam body 1 more stable. The side wall of the groove 11 can limit the side wall body 2, thereby preventing the side wall body 2 from moving relative to the upper side beam body 1, thereby effectively improving the overall stability of the vehicle body.

[0037] Furthermore, an anti-slip groove 111 may be provided on the side wall of the groove 11 , and the side wall body 2 may be provided with an anti-slip protrusion 21 for cooperating with the anti-slip groove 111 .

[0038] like Figure 4 As shown, the cross-section of the anti-slip protrusion 21 is a right triangle, one right-angled side of the right triangle is in contact with the side wall body 2, the other right-angled side of the right triangle is perpendicular to the side wall body 2, the end of the hypotenuse of the right triangle close to the top of the side wall body 2 is in contact with the side wall body 2, and the other end of the hypotenuse of the right triangle is connected to the right-angled side perpendicular to the side wall body 2.

[0039] During the actual assembly process, when the side wall body 2 is inserted into the groove 11 of the upper side beam body 1, the inclined surface where the hypotenuse of the anti-slip protrusion 21 is located can play a guiding role. After the anti-slip protrusion 21 cooperates with the anti-slip groove 111, when the side wall body 2 is pulled out, the right-angled side of the anti-slip protrusion 21 cooperates with the anti-slip groove 111, which can effectively prevent the side wall body 2 from accidentally slipping out.

[0040] Of course, the anti-slip protrusion 21 can also be set to other shapes that meet the requirements, which is determined according to actual conditions and will not be described in detail here.

[0041] In this specific embodiment, after the upper side beam body 1 and the side wall body 2 are plugged together, a stable anti-slip structure is formed, which greatly improves the anti-slip performance of the connection. The design of the anti-slip structure does not hinder the plug-in assembly, and a stable anti-slip structure is formed after being plugged in place.

[0042] During the actual assembly process, the part of the side wall body 2 inserted into the groove 11 is provided with a first mounting hole, the upper side beam body 1 is provided with a second mounting hole 112 for cooperating with the first mounting hole, and the rail vehicle body also includes rivets passing through the first mounting hole and the second mounting hole 112.

[0043] During the assembly process, the outer wall of the side wall body 2 can be bonded and connected to the inner wall of the groove 11 of the upper side beam body 1. At the same time, the rivet is passed through the first mounting hole and the second mounting hole 112, and the side wall body 2 and the upper side beam body 1 are fixedly connected by the rivet. The rivet serves as the main bearing member, and the bonding connection and the plug-in connection setting method can further improve the stability of the connection between the side wall body 2 and the upper side beam body 1.

[0044] On the basis of the above embodiment, a door angle structure 22 may be provided at one end of the side wall body 2 inserted into the groove 11 , and the door angle structure 22 is provided with a positioning surface for fitting with the bottom surface of the groove 11 .

[0045] like Figure 6 As shown, the door corner structure 22 is provided with a first connecting hole 221, the bottom surface of the groove 11 in the upper side beam body 1 is provided with a second connecting hole for cooperating with the first connecting hole 221, and the rail vehicle body also includes a connecting member passing through the first connecting hole 221 and the second connecting hole.

[0046] In this specific embodiment, the door corner structure 22 is connected to the upper side beam body 1 by a connecting piece. During the connection process, the connecting piece serves as the main bearing member, which can effectively improve the firmness of the connection compared to the connection method that only relies on bonding in the prior art.

[0047] Specifically, the first connecting member may be a connecting pin, a connecting screw or a connecting bolt, etc.

[0048] A transition arc surface 222 may also be provided at the connection between the door corner structure 22 and the side wall body 2 , so that the door corner structure 22 and the side wall body 2 are an integrated structure.

[0049] Compared with the assembly method in the prior art, in this specific embodiment, the door corner structure 22 and the side wall body 2 are set as an integrated structure, which can avoid the risk of failure of the connection between the door corner structure 22 and the side wall body 2 during the actual assembly process, and significantly improve the structural strength of the door corner structure 22. At the same time, the upper plane of the door corner structure 22 is used as the assembly surface and as the stop surface during the plugging process. During the plugging process, the upper plane of the door corner structure 22 fits the assembly surface in the upper side beam body 1, which is the assembled state, and plays the role of plugging and positioning, which is convenient for the side wall body 2 and the upper side beam body 1 to be quickly and accurately positioned.

[0050] Furthermore, the side wall body 2 can be set as a side wall body 2 made of carbon fiber composite material; the bottom surface of the groove 11 in the upper side beam body 1 is provided with a positioning portion for positioning the installation position of the side wall body 2 .

[0051] During the actual assembly process, the positioning portion can be set as a positioning protrusion or a positioning groove 11, and a positioning structure for cooperating with the positioning portion can be set on the side wall body 2. When the side wall body 2 is inserted into the groove 11 of the upper side beam body 1, it is positioned by the positioning portion and the positioning structure to limit the installation position of the side wall body 2 relative to the upper side beam body 1.

[0052] like Figure 7 As shown, it is a mounting fixture 3 for assembling the side wall body 2 and the upper side beam body 1 in the present application document. The mounting fixture 3 includes a first positioning device 31, a base frame 32 and a sliding device 33. The specific assembly process includes: workpiece pre-assembly → connection surface separation → gluing → restoration assembly → riveting.

[0053] First, the upper side beam body 1 needs to be installed to the first positioning device 31 of the installation fixture 3 to restrict the upper side beam from forming a tendency of bending upward in the middle part, thereby improving the overall rigidity of the large side wall component;

[0054] The first positioning device 31 is provided with a presser 311, and the specific structure of the presser 311 is as follows: Figure 8 As shown, in the actual assembly process, the upper side beam body 1 needs to be placed on the follower 312, and the upper side beam body 1 needs to be pressed and fixed by the clamp 311; then, the side wall body 2 is sequentially loaded into the corresponding sliding device 33, and the side wall body 2 slides with the sliding device 33 through the side, bottom, and window constraints of the side wall body 2, so that the upper part of the side wall body 2 is inserted into the groove 11 of the upper side beam body 1 for assembly. Under the action of the spiral rocker, the sliding device 33 translates along the Y-axis direction, driving the side wall body 2 to advance and withdraw; by operating the rocker, the sliding device 33 drives the side wall body 2 to be pushed into the U-shaped groove 11 of the upper side beam body 1, and the positioning size of the side wall body 2 is fine-tuned in combination with the screw device on the sliding device 33. After all dimensions are re-inspected and qualified, the pre-research and matching process is completed. Next, operate the rocker, and the sliding device 33 drives the side wall body 2 to withdraw from the upper side beam body 1, and proceed to the next step of gluing the connecting surface; finally, operate the rocker, and the sliding device 33 drives the side wall body 2 to advance into the U-shaped groove 11 of the side beam, complete the restoration of positioning, and then perform formal riveting to form the final side wall structure.
