Problems solved by technology
Because the material of the corner parts is relatively thick, the closed loop formed by the corner parts at the bottom of the carriage will raise the carriage, causing water to accumulate at the bottom of the carriage. Most carriage manufacturers realize the waterproof function by applying sealant on the contact surface between the bottom plate and the wrapping angle. Such a waterproof structure has problems such as poor waterproof performance and the sealant is easily corroded by water at the bottom of the carriage. Once the sealant After being corroded, the bottom of the compartment loses its waterproof function

The waterproof connecting structure at the bottom of the carriage comprises a first connecting piece and a second connecting piece, the top face of the first connecting piece is connected with a side plate of the carriage, the bottom face of the first connecting piece is connected with the top face of the second connecting piece, a first connecting plate is arranged on the top face of the second connecting piece, and the first connecting plate is connected with the first connecting piece. A second connecting plate is arranged at the top of the first connecting plate, and the top face of the second connecting plate is connected with a compartment bottom plate. The waterproof connecting structure is arranged between the carriage side plate and the carriage bottom plate, accumulated water can be effectively prevented from entering the carriage from the position between the carriage side plate and the carriage bottom plate, and the first connecting plate and the second connecting plate are additionally arranged on the waterproof connecting structure, so that the accumulated water can be effectively prevented from entering the carriage from the joint of the first connecting piece and the second connecting piece; and the waterproof performance of the carriage is improved.
Description
technical field [0001] The invention relates to the field of carriage manufacturing, in particular to a waterproof connection structure at the bottom of a carriage. Background technique [0002] The carriage is generally a hexahedron structure, which is mainly assembled by six panels and eight corner pieces, and the connection between the two panels is connected by the corner pieces. Because the material of the corner parts is relatively thick, the closed loop formed by the corner parts at the bottom of the carriage will raise the carriage, causing water to accumulate at the bottom of the carriage. Most carriage manufacturers realize the waterproof function by applying sealant on the contact surface between the bottom plate and the wrapping angle. Such a waterproof structure has problems such as poor waterproof performance and the sealant is easily corroded by water at the bottom of the carriage. Once the sealant After being corroded, the bottom of the compartment loses its...
