The invention discloses a waterproof mechanism for an automobile exhaust pipe, which includes a connecting rod device and a drainage device, and the movement of the transmission device controls the closing and opening of the exhaust pipe passage by the drainage device, and is characterized in that: the waterproof mechanism is also It includes an electromagnetic device, and the different moving directions of the connecting rod device are driven by the switching of the electromagnetic device. The waterproof mechanism in the present invention mainly controls the opening and closing of the exhaust pipe by using the electromagnetic force, the expansion force of the spring, the exhaust gas force of the exhaust pipe, and the backflow pressure of the water backflow to prevent the water backflow. Frequent disassembly brings great convenience to people.
Description
Technical field: [0001] The invention relates to the technical field of an automobile exhaust pipe, in particular to a waterproof mechanism for an automobile exhaust pipe. Background technique: [0002] A car, in a broad sense, is a four-wheeled vehicle driven by its own power plant and non-rail-driven. A car is composed of multiple system components. The car exhaust pipe is one of the main components of the car. Its main function is to discharge the exhaust gas from the car engine, and the car exhaust pipe cannot enter water. However, when the automobile exhaust pipe in the prior art is protected, the protection is not ideal. In rainy days or when the vehicle passes through some seriously waterlogged roads, the exhaust pipe cannot be drained and sealed in time, causing the exhaust pipe to easily enter water, the protection effect is not ideal, the vehicle ceases to fire, and the power of the car is affected. In severe cases, it may even cause the car to break down. If the...
