Anti-cracking drain channel structure and mounting method

Abstract

The invention discloses an anti-cracking drain channel structure. The anti-cracking drain channel structure comprises front shock absorber seat connecting plates (11), an automobile drain channel main body (2) and pi-shaped brackets (1), wherein plug welding holes (12) are formed in the front ends and the back ends of the pi-shaped brackets (1); mounting screw holes are formed in the top ends of the pi-shaped brackets (1); by using bolts, the two pi-shaped brackets (1) are fixedly connected with the automobile drain channel main body (2) at the two ends of the automobile drain channel main body (2) through the mounting screw holes (3); the two pi-shaped brackets (1) are fixed on the front shock absorber seat connecting plates (11) through respective front and back plug welding holes (12). The anti-cracking drain channel structure disclosed by the invention is advantaged in that the structure of the anti-cracking drain channel structure is simple and practical, the space occupied by the anti-cracking drain channel structure is small, the anti-cracking drain channel structure is convenient to mount and detach and the NVH (Noise Vibration and Harshness) performance of the whole automobile can be improved.

Description

Technical field [0001] The invention belongs to the technical field of automobile manufacturing, and particularly relates to a novel anti-cracking automobile running water tank structure. Background technique [0002] The car body drain is an important part of the vehicle. The main function of the body drain is to drain rainwater from the body along the rail groove to the outside of the car, preventing water from flowing into the interior of the car body and the interior of the body sheet metal structure, providing a comfortable interior space and To prevent premature corrosion of the body sheet metal under the action of rain, a reasonable design of the water tank structure is very important. The common structure types of automobile flow tank are divided into two structural forms: inner package and external leakage front shock absorber seat. The most common domestic automobile flow tank structure type is that the front shock absorber seat is outside the flow tank, which belongs t...

Problems solved by technology

Regardless of the exposed type or the inner type, the common feature is that the two ends of the water tank are bolted or welded to the cover hinge mounting plate, which makes it difficult or deformed to stamp at the overlapping joints of the two ends of the water tank. The stamping deformation is the direct fuse of the road test cracking. At the same time, the water tank belongs to the front cabin of the car. If the body performance of the water tank body does not meet the requirements, it will directly affect the performance of the wiper system, which is also an important factor affecting the NVH performance of the car body. It is a fatigue and durability problem that is easily caused by the overlapping joints at both ends of the water tank. Sometimes in order to meet the performance requirements of the vehicle body, the design of the water tank is usually thicker or the reinforcement plate of the water tank is added to meet the roll stiffness and durability. At the same time, the weight of the vehicle body Increase, the cost of car manufacturing increases, even for models on the same platform, due to the requirements of vehicle quality, mold cycle and cost, the flow tank has to be redesigned, resulting in poor versatility of the flow tank

[0003] Due to the insufficient roll stiffness and durability of the existing water tanks, the thickness of the water tank design or the addition of water tank reinforcement plates to meet the performance requirements of the vehicle body. At the same time, the structure and roll stiffness requirements of different vehicle models are different. The versatility of the sink is poor
