Description

Technical Field

[0001] This invention belongs to the field of vehicle body manufacturing technology, and specifically relates to an assembly structure for freight car bodies. Background Technology

[0002] The cargo box is generally a hexagonal structure, mainly assembled from six panels and eight corner brackets. During panel assembly, the joints between two panels are connected by the corner brackets. To prevent water from entering the cargo box, the existing waterproofing structure involves applying sealant to the contact surfaces between the corner brackets and the top (or bottom) panel. This waterproofing structure suffers from drawbacks such as weak waterproofing measures, poor waterproofing performance, and the sealant being easily corroded by water accumulation inside the cargo box. Once the sealant is corroded, the cargo box loses its waterproofing function. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an assembly structure for a truck body, including a truck body roof, truck body side panels, and a truck body floor. A top waterproof structure is provided between the truck body roof and the truck body side panels. The top waterproof structure includes a first top partition, a second top partition, and a third top partition. The first top partition is a C-shaped component. The upper surface of the first top partition is connected to the truck body roof, and the lower surface of the first top partition is connected to the truck body side panels. The second top partition is connected to the side of the first top partition. The third top partition is located between the first top partition and the truck body side panels and is in contact with the lower part of the second top partition.

[0004] A bottom waterproof structure is provided between the side panel and the floor of the carriage. The bottom waterproof structure includes a first bottom partition, a second bottom partition, and a third bottom partition. The first bottom partition is located between the side panel and the floor of the carriage and is a Z-shaped piece. The second bottom partition is located between the first bottom partition and the side panel of the carriage. The upper surface of the first bottom partition is connected to the floor, and the third bottom partition is provided on the floor.

[0005] Preferably, the upper surface of the first top partition is provided with a top water-retaining fin.

[0006] Preferably, the lower surface of the first top partition is provided with a flow-draining baffle.

[0007] Preferably, the second top partition is connected to the side of the first top partition by rivets, the rivets being located in rivet holes on the first top partition.

[0008] Preferably, the contact area between the second top partition and the third top partition is waterproofed and sealed.

[0009] Preferably, the side of the third bottom partition is provided with a bottom water-blocking flange, which is in contact with and connected to the side panel of the carriage.

[0010] Preferably, the connection between the third bottom partition and the floor is sealed and waterproofed.

[0011] Preferably, a first cavity is provided above the side panel of the carriage, and a first reinforcing member is provided in the first cavity, which is connected to the third top partition.

[0012] Preferably, a second cavity is provided below the side panel of the carriage, and a second reinforcing member is provided in the second cavity, the second reinforcing member being connected to the second bottom partition.

[0013] Beneficial effects: This invention discloses an assembly structure for truck bodies. Compared with existing truck body waterproofing technologies, this invention effectively prevents water from entering the truck body from the connection between the truck body roof and side panels, and the connection between the truck body side panels and the truck body floor by adding a top waterproofing structure and a bottom waterproofing structure between the truck body roof, side panels and floor, thereby improving the waterproofing performance of the truck body.

[0018] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0019] like Figures 1-3As shown, an assembly structure for a truck body includes a roof panel 1, side panels 2, and a floor panel 3. A waterproof top structure 4 is provided between the roof panel 1 and the side panels 2. The waterproof top structure 4 includes a first top partition 41, a second top partition 42, and a third top partition 43. The first top partition 41 is a C-shaped component. The upper surface of the first top partition 41 is connected to the roof panel 1, and the lower surface of the first top partition 41 is connected to the side panels 2. The upper surface is provided with a top water-blocking edge 411, and the lower surface of the first top partition 41 is provided with a drainage baffle 412. The second top partition 42 is connected to the side of the first top partition 41 by rivets, and the rivets are located in the rivet holes 413 on the first top partition 41. The third top partition 43 is located between the first top partition 41 and the side panel 2 of the carriage, and is in contact with the lower part of the second top partition 42. The contact point between the second top partition 42 and the third top partition 43 is waterproof and sealed.

[0020] A bottom waterproof structure 5 is provided between the side panel 2 and the floor 3 of the carriage. The bottom waterproof structure 5 includes a first bottom partition 51, a second bottom partition 52 and a third bottom partition 53. The first bottom partition 51 is located between the side panel 2 and the floor 3 of the carriage and is a Z-shaped piece. The second bottom partition 52 is located between the first bottom partition 51 and the side panel 2 of the carriage. The upper surface of the first bottom partition 51 is connected to the floor 6. The third bottom partition 53 is provided on the floor 6. The side of the third bottom partition 53 is provided with a bottom water-blocking edge 54. The bottom water-blocking edge 54 is in contact with the side panel 2 of the carriage. The connection between the third bottom partition 53 and the floor 6 is sealed and waterproofed.

[0021] A first cavity 21 is provided above the side panel 2 of the carriage, and a first reinforcing member 22 is provided inside the first cavity 21. The first reinforcing member 22 is connected to the third top partition 43. A second cavity 23 is provided below the side panel 2 of the carriage, and a second reinforcing member 24 is provided inside the second cavity 23. The second reinforcing member 24 is connected to the second bottom partition 52.

[0022] Top working status: such as Figure 1 As shown, the water that seeps into the carriage from the top plate 1 will pass through the upper surface of the first top partition 41, the side of the first top partition 41, and the lower surface of the first top partition 41 in sequence, and flow out between the drainage baffle 412 and the carriage side plate 2.

[0023] Bottom working status: such as Figure 2 and Figure 3As shown, when there is water accumulation at the bottom of the carriage, the water will enter the bottom waterproof structure 4 through the gap between the first bottom partition 51 and the side panel 2 of the carriage. When there is too much water accumulation at the bottom of the carriage, in order to prevent water from entering the carriage, a bottom water-blocking flange 54 is provided on the side of the third bottom partition 53, and a water-accumulating gap is formed between the bottom water-blocking flange 54 and the side panel 2 of the carriage. When the water accumulation at the bottom of the carriage decreases, the water in the side panel 2 and the bottom panel 3 of the carriage flows out along the water inlet path.
