DETAILED DESCRIPTION

[0036] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0037] The end wall structure of the present application will be described below in combination with Figures 1 to 6 The end wall structure of the present application can be applied to a vehicle body, and the two side edges thereof are adapted to be connected with side walls, the top thereof is adapted to be connected with a roof, and the bottom thereof is adapted to be connected with a chassis. After the end wall structure is applied to the vehicle body, one side thereof faces the interior of the vehicle body, and the other side thereof faces the exterior of the vehicle body. For the convenience of understanding, the side facing the exterior of the vehicle body will be described as the vehicle exterior side, and the side facing the interior of the vehicle body will be described as the vehicle interior side.

[0038] The end wall structure can be connected with the through channel by setting a mounting structure. Specifically, the end wall body 100 is provided with an end door opening 400, and the mounting structure can be arranged on the vehicle exterior side of the end wall body 100 and located on the circumferential side of the end door opening 400. It can be understood that when the size of the through channel changes, the arrangement position of the mounting structure also changes correspondingly, and the end wall structure of the present embodiment can well adapt to the position change of the mounting structure.

[0039] As shown in Figures 1 to 3 According to the end wall structure of the present embodiment, the end wall structure comprises an end wall body 100, the end wall body 100 comprises a plurality of end wall profiles, adjacent end wall profiles are connected and fixed, and the connection can be achieved by, for example, welding, riveting or the like. The end wall profiles can limit an end door opening 400 inside the end wall structure.

[0040] At least one of the end wall profiles located at the side of the end door opening 400 is provided with a built-in groove 121, which is used to set up a through passage installation structure, specifically, a keyhole can be set up on the outer side of the end wall profile corresponding to the position of the built-in groove 121, and a rivet nut is arranged.

[0041] The built-in groove 121 extends along the parallel direction of the adjacent side edges of the end door opening 400, and the built-in grooves 121 on the same end wall body 100 are spaced apart in a direction away from the end door opening 400. Taking the built-in groove 121 adjacent to the right side edge of the end door opening 400 as an example, the built-in groove 121 extends in a direction parallel to the right side edge of the end door opening 400, that is, in a vertical direction, and the built-in groove 121 is spaced apart in a direction away from the right side edge of the end door opening 400 (horizontal direction). It can be understood that in the same built-in groove 121, any position of the built-in groove 121 in the extension direction can be used as a setting position of the installation structure, and in different built-in grooves 121, the installation structure can be set in any built-in groove 121 according to the position requirement. It can be seen that the end wall structure of the embodiment of the present application can better adapt to the position change of the installation structure of the through passage, thereby adapting to the change of the installation size of the through passage.

[0042] In the embodiment of the present application, each end wall profile can adopt an integral molding structure, and further, the built-in groove 121 can be a recess structure integrally formed in the end wall profile.

[0044] In the embodiment, the constituent plates 123 are arranged in a direction perpendicular to the side wall of the end wall profile, and the constituent plates 123 in the same end wall profile are parallel to each other, thereby forming the built-in groove 121 structure with the same width at each position of the extension path.

[0045] Optionally, the inner cavity 122 of the same end wall profile is provided with a plurality of constituent plates 123, and the built-in groove 121 is formed between adjacent constituent plates 123.

[0046] Optionally, the constituent plate 123 is provided with a limiting portion 124, and the limiting portions 124 between the pair of constituent plates 123 are oppositely arranged. The limiting portion 124 can limit the installation depth of the installation structure, and has a positioning purpose.

[0047] In the embodiment, the constituting plate 123 can be a partition plate connecting two opposite side walls of the end wall profile, or can be a side plate connecting only one side outside the vehicle. It is worth noting that in the end wall structure of the embodiment, not all the partition plates inside the end wall profile for increasing the strength of the structure are necessarily used as the constituting plate 123, that is, at least part of the partition plates are used as the constituting plate 123 of the embodiment.

[0048] According to the end wall structure of the embodiment, the plurality of end wall profiles includes a pair of end wall beams 110 and a pair of door uprights 120. The end wall beams 110 are arranged horizontally, and the pair of end wall beams 110 are arranged in the vertical direction. For the convenience of description, the upper end wall beam 110 is named as the upper door beam, and the lower end wall beam 110 is named as the lower door beam. The pair of door uprights 120 are oppositely arranged and are both fixedly arranged between the pair of end wall beams 110. For the convenience of description, the left door upright 120 is named as the left door column, and the right door upright is named as the right door column. Figure 1

[0049] The pair of end wall beams 110 and the pair of door uprights 120 enclose the end door opening 400. Specifically, the upper door beam, the lower door beam, the left door column, and the right door column constitute the upper side frame, the lower side frame, the left side frame, and the right side frame of the end door opening 400, respectively.

[0050] At least one of the door uprights 120 and / or at least one of the end wall beams 110 is provided with an embedded groove 121. For example, the upper door beam, the lower door beam, the left door column, and the right door column are respectively provided with the embedded groove 121, or the left door column and the right door column are respectively provided with the embedded groove 121, and the like, which can be flexibly selected according to the needs, and will not be listed one by one here.

[0051] It can be understood that when the upper door beam and the lower door beam are provided with the embedded groove 121, the embedded groove 121 of the upper door beam and the lower door beam extends in the horizontal direction and is arranged in the vertical direction at intervals. When the left door column and the right door column are provided with the embedded groove 121, the embedded groove 121 of the left door column and the right door column extends in the vertical direction and is arranged in the horizontal direction at intervals.

[0052] In some embodiments of the present application, the end wall beam 110 includes an integrally formed beam body 111 and a connecting portion 112 arranged at both ends of the beam body 111. The connecting portion 112 is arranged at an angle with the beam body 111, the included angle between the connecting portion 112 and the beam body 111 constitutes a corner of the end door opening 400, and the connecting portion 112 is fixedly connected with the corresponding door upright 120.

[0053] In the embodiment, the included angle between the connecting portion 112 and the beam body 111 is preferably 90°, and the included angle formed between the connecting portion 112 and the beam body 111 preferably adopts a rounded corner structure.

[0054] ​Taking the upper door beam in the end wall transverse beam 110 as an example, two connecting portions 112 are located at the lower side of both ends of the transverse beam body 111, and the connecting portion 112 located at the left side is connected and fixed with the upper end of the left door column, and the connecting portion 112 located at the right side is connected and fixed with the upper end of the right door column.

[0055] It is worth mentioning that the joint position of the door column and the transverse beam of the end wall commonly used in the prior art is flush with the upper side of the door, which has weak strength. The present application integrates the design of the upper door and the lower door profiles, and the door corner is directly brought out by the profile, replacing the original welding structure, which can simplify the end wall structure, change the stress condition of the door corner position, and improve the overall structural strength.

[0056] Referring to Figure 2 Optionally, an adhesive filler plate 500 is arranged at the position of the included angle between the connecting portion 112 and the transverse beam body 111, and the adhesive filler plate 500 extends to the side wall of the door stand column 120.

[0057] The adhesive filler plate 500 is designed according to the shape of the position of the included angle formed by the connecting portion 112 and the transverse beam body 111, and is fixed at the position of the included angle by an adhesive. One end of the adhesive filler plate 500 extends to the door stand column 120, and the adhesive filler plate 500 and the door stand column 120 are in adhesive cooperation at the position.

[0058] In the embodiment, the adhesive filler plate 500 not only strengthens the structure of the position of the included angle, but also spans two profiles, so as to seal the joint between the end wall transverse beam 110 and the door stand column 120, and enhance the connection strength of the end wall transverse beam 110 and the door stand column 120. In addition, the adhesive filler plate 500 is connected with the end wall transverse beam 110 and the door stand column 120 by adhesion, which is different from the welding connection between the end wall transverse beam 110 and the door stand column 120, so as to further improve the stress condition and enhance the structural strength.

[0059] Referring to Figure 3 Optionally, a stepped connection structure is adopted between the end wall transverse beam 110 and the door stand column 120, that is, the thickness of the end wall transverse beam 110 and the door stand column 120 at the connection position is different, for example Figure 3 As shown in FIG. 8, the thickness of the end connected with the connecting portion 112 is greater than the thickness of the end connected with the connecting portion 112. In this way, stress concentration can be avoided.

[0060] Optionally, the end of the connecting part 112 connected with the door upright post 120 is provided with a welding joint 113, and a gap is formed between the welding joint 113 and the side wall of the connecting part 112, which is suitable for lap joint with the side plate of the welding joint 113. By lap joint and welding of the welding joint 113 and the door upright post 120, the connection strength of the connecting part 112 and the door upright post 120 can be improved, and the alignment of the door upright post 120 and the side wall of the connecting part 112 can be facilitated.

[0061] Optionally, the end of the connecting part 112 connected with the door upright post 120 gradually increases in thickness in the direction close to the door upright post 120, so as to locally strengthen the connecting part 112 and improve the structural strength.
