[0042] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] refer to Figures 1-5 An embodiment of this utility model shows a connection structure between a vertical beam and a car bottom, including a car bottom 1, a vertical beam 2, a side connector 3, and a bottom connector 4;

[0045] The upright beam 2 is disposed on the side of the car bottom 1; the side connector 3 includes a first connecting plate 31 and a second connecting plate 32, the first connecting plate 31 is connected to the side of the car bottom 1, and the second connecting plate 32 is connected to the side of the upright beam 2; the bottom connector 4 includes a support plate 41 disposed at the bottom of the upright beam 2, two third connecting plates 42 extending upward from both sides of the support plate 41, the third connecting plates 42 being connected to the side of the upright beam 2, and a fourth connecting plate 43 extending laterally from the third connecting plate 42, the fourth connecting plate 43 being supported at the bottom of the car bottom 1.

[0046] Among them, the side connector 3 can realize the side connection between the upright beam 2 and the car bottom 1. At the same time, the fourth connecting plate 43 of the bottom connector 4 directly supports the car bottom 1, reducing the risk of sheet metal parts such as the side connector 3 being easily torn under high load. In addition, the support plate 41 and the third connecting plate 42 on the bottom connector 4 form a U-shaped structure, which can simultaneously withstand the vertical pressure, horizontal shear force and overturning moment from the car bottom 1, avoiding stress concentration caused by a single bolt group bearing the load, and avoiding bolt breakage.

[0047] In the above scheme, such as Figure 2 and Figure 5As shown, the upright beam 2 is arranged along the vertical direction Z, while the side of the car bottom 1 (referring to the side of the car bottom 1 connected to the upright beam 2) is arranged along the first direction X. To achieve the support of the bottom connector 4 for the car bottom 1, at least a portion of the bottom connector 4 extends relative to the upright beam 2 in the second direction Y, that is, the length of the bottom connector 4 in the second direction Y should be greater than the length of the upright beam 2 in the second direction Y, so that the bottom connector 4 can be supported at the bottom of the car bottom 1. Herein, the first direction X and the second direction Y are two mutually perpendicular directions on the horizontal plane. Therefore, in this embodiment, the upright beam 2, the car bottom 1, and the bottom connector 4 can form a three-dimensional spatial cross connection in the vertical direction Z, the first direction X, and the second direction Y, thereby improving the resistance to shear force in any single direction. Even if the connection in any direction breaks, the connection in the remaining two directions can still ensure the connection stability of the upright beam 2 and the car bottom 1. Furthermore, based on the above connection structure, the connection is strengthened by the side connector 3, further ensuring that the overall connection strength is high enough.

[0048] In addition, such as Figure 4 and Figure 5 As shown, in this embodiment, the bottom of the bottom connector 4 can be used to install the safety clamp 100, specifically by installing the safety clamp 100 to the bottom of the tray 41. Since the bottom connector 4 extends in the second direction Y, it can provide sufficient installation space for the safety clamp 100 and improve the connection stability between the safety clamp 100 and the upright beam 2.

[0049] In some embodiments, such as Figure 3 As shown, there are two side connectors 3, located on both sides of the upright beam 2. The first connecting plate 31 and the second connecting plate 32 are vertically arranged. In this embodiment, the side connectors 3 are L-shaped sheet metal, and both the first connecting plate 31 and the second connecting plate 32 are vertically arranged in a Z-shape. The two side connectors 3 are symmetrically arranged on both sides of the upright beam 2 to improve the stress balance.

[0050] Specifically, the above scheme is as follows: Figure 3 As shown, the first connecting plate 31 of the side connector 3 is connected to the side of the car bottom 1 via a first bolt assembly 5, and the second connecting plate 32 is connected to the side of the upright beam 2 via a second bolt assembly 6. The first bolt assembly 5 is arranged along the second direction Y, and the second bolt assembly 6 is arranged along the first direction X. The first bolt assembly 5 and the second bolt assembly 6 work together to bear the vertical Z-force, and each bears tensile forces in different directions, achieving optimized load distribution.

[0051] Multiple first bolt assemblies 5 and multiple second bolt assemblies 6 can be provided as needed to meet the connection strength requirements.

[0052] In some embodiments, such as Figure 3 As shown, the support plate 41, the third connecting plate 42, and the fourth connecting plate 43 are vertically and integrally connected in sequence. The U-shaped structure formed by the support plate 41 and the third connecting plate 42 has reliable bending stiffness, and at the same time, the U-shaped structure can provide sufficient support for the fourth connecting plate 43 to achieve stable support for the car bottom 1.

[0053] Specifically, the above scheme is as follows: Figure 3 As shown, the third connecting plate 42 is connected to the side of the upright beam 2 via the third bolt assembly 7, and the fourth connecting plate 43 is connected to the bottom of the car floor 1 via the fourth bolt assembly 8. The third bolt assembly 7 is positioned along the first direction X, and the fourth bolt assembly 8 is positioned along the vertical direction Z. The third bolt assembly constrains the lateral displacement of the upright beam 2, and the fourth bolt assembly restricts the vertical separation of the car floor 1. Thus, the upright beam 2 and the car floor 1 are connected by the first bolt assembly 5, the second bolt assembly 6, the third bolt assembly 7, and the fourth bolt assembly 8. These four bolt assemblies provide locking in multiple directions, including vertical Z, first direction X, and second direction Y. Even if a bolt assembly in any one direction breaks, the bolt assemblies in other directions can maintain the connection between the upright beam 2 and the car floor 1, preventing the connection from breaking.

[0054] Multiple third bolt assemblies 7 and multiple fourth bolt assemblies 8 can be provided depending on the specific circumstances, in order to meet the connection strength requirements.

[0055] In the above scheme, the upright beam 2 adopts C-shaped sheet metal, and the C-shaped upright beam 2 provides a high cross-sectional moment of inertia, maintaining a balance between lightweight and strength.

[0056] In summary, this application provides a connection structure between the upright beam and the car floor. This connection structure achieves the connection between the car floor 1 and the upright beam 2 through the side connector 3 and the bottom connector 4. The side connector 3 enables the side connection between the upright beam 2 and the car floor 1. At the same time, the fourth connecting plate 43 of the bottom connector 4 directly supports the car floor 1, reducing the risk of sheet metal parts such as the side connector 3 being easily torn under high load. In addition, the support plate 41 and the third connecting plate 42 on the bottom connector 4 form a U-shaped structure, which can simultaneously withstand the vertical pressure, horizontal shear force and overturning moment from the car floor 1, avoiding stress concentration caused by a single bolt group bearing the load and preventing bolt breakage.

[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
