The utility model relates to an automobile door lock reinforcement waterproof structure, which comprises an automobile door inner plate, a door lock reinforcement and a door lock; the door lock reinforcement is provided with a second lock pin through hole, the door lock reinforcement is welded on the inner door plate, and the door lock is installed on the door lock reinforcement and the inner door plate through bolts; the door lock reinforcement and the inner plate of the vehicle door are sealed by welding sealant; and foam is arranged between the door lock and the door lock reinforcement to prevent water from flowing to the fish mouth position of the inner plate of the vehicle door from the space between the door lock reinforcement and the door lock. By arranging the foam between the door lock and the door lock reinforcement, water which can enter between the door lock and the door lock reinforcement can be guided to be discharged from two ends of the foam, and cannot flow to the fish mouth position of the inner plate of the vehicle door.

As a further improvement to the present invention, the foam is located on the second lock pin via hole upside. The foam is arranged on the upper side of the second lock pin through hole, so that water can be prevented from flowing into the second lock pin through hole.

As a further improvement, the length of the two ends of the foam far exceeds the left and right length of the second lock pin via hole. Adopt above-mentioned technical scheme's purpose to guarantee that water flows out from the both ends of steeping cotton.

As a further improvement of the present invention, the door inner panel includes a first lock pin through hole, the door lock reinforcement further has a lock body mounting hole, a glue coating groove communicated with the left and right edges of the door lock reinforcement is provided between the upper edge of the door lock reinforcement and the lock body mounting hole, and the welding sealant is provided in the glue coating groove and is bonded with the door inner panel; the second lock pin through hole is consistent with the first lock pin through hole in outline and corresponds to the first lock pin through hole in position.

As a further improvement, the drainage channel is arranged at the lower part of the door lock reinforcement. Establish water drainage tank and can guarantee that the water that flows into between door lock reinforcement and the door inner panel from the side flows out from water drainage tank, prevents ponding water after certain degree from door inner panel fish mouth position outflow.

The utility model has the advantages of it is following: the waterproof structure can prevent water from leaving the first lock pin through hole between the door lock and the door lock reinforcement, namely, prevent water from flowing to the fish mouth position of the inner plate of the vehicle door, obviously improve the experience of a user, and simultaneously prevent accumulated water between the door lock and the door lock reinforcement from corroding the door lock reinforcement; because the welding sealant is arranged between the door lock reinforcement and the inner door plate, water can be prevented from flowing into the first lock pin through hole from the space between the door lock reinforcement and the inner door plate, and meanwhile, the problem of corrosion caused by accumulated water to the door lock reinforcement and the inner door plate can be prevented; this waterproof construction establishes the water drainage tank in the outside of lock reinforcing plate lower part, can guarantee to flow into the water between lock reinforcement and the door inner panel from the side and flow out from the water drainage tank.
