[0027] It should be noted that the drawings provided in the following embodiments only schematically illustrate the basic concept of the present application, and the drawings only show the components related to the present application, not the number, shape and size of the components when actually implemented. The shape, number and ratio of the components when actually implemented can be changed at will, and the layout pattern of the components can also be more complex.

[0028] The specific embodiments of the present application will be further described below with reference to the accompanying drawings.

[0029] The present application discloses a snow-preventing intake pipe structure for a vehicle, as shown in Figure 1 and Figure 4As shown, including the upper intake pipe 1, lower intake pipe 2 and connecting pipe 3, upper intake pipe 1 and connecting pipe 3 fixed connection, connecting pipe 3 and lower intake pipe 2 fixed connection, upper intake pipe 1 inside is provided with the baffle 4 which is in contact with the inner wall of upper intake pipe 4, the baffle 4 is provided with drive shaft 5, upper intake pipe 1 side is provided with through hole 6, drive shaft 5 passes through the through hole 6 and is connected with actuator 7, one side of connecting pipe 3 is provided with air inlet 8, specifically, actuator 7 connects drive shaft 5, drive shaft 5 drives baffle 4 to rotate, plays a role in closing upper intake pipe 1 or air inlet 8, prevent rain and snow into air filter.

[0030] The actuator 7 is fixed on one side of the upper intake pipe 1 and the connecting pipe 3 through the actuator support 9, and the actuator 7 support is composed of a first support column 90, a second support column 91 and a third support column 92. The first support column 90 is arranged outside the upper intake pipe 1, and the second support column 91 and the third support column 92 are arranged on both sides of the connecting pipe 3. Such design makes the connection of the upper intake pipe 1 and the connecting pipe 3 more stable, and the actuator 7 does not need to be fixed additionally, thereby reducing the production cost.

[0031] The upper intake pipe 1 and the connecting pipe 3 are fixedly connected through buckles, and the connecting pipe 3 and the lower intake pipe 2 are fixedly connected through buckles. The buckle design is simple to install and low in manufacturing cost, which can reduce the production cost and is convenient to disassemble.

[0032] The upper air inlet 8 is composed of an air inlet pipe upper shell 10 and an air inlet pipe lower shell 11. The air inlet pipe upper shell 10 is fixed on the air inlet pipe lower shell 11 through buckles. When overhauling, the internal structure can be clearly seen without the need to disassemble the whole, which is more convenient and fast.

[0033] A ring-shaped protrusion 12 for limiting is arranged inside the upper intake pipe 1 near one side of the connecting pipe 3 and the middle of the baffle 4. Since the baffle 4 can rotate, the ring-shaped protrusion 12 can play a limiting role. The ring-shaped protrusion 12 can make the baffle 4 better close the upper intake pipe 1, block the rain and snow and sundries entering the upper intake pipe 1.

[0034] One end of the upper intake pipe 1 is provided with a fixed plate 13. A first reinforcing rib 14 is arranged on the outer side of the upper surface of the fixed plate 13. A second reinforcing rib 15 is arranged on the inner side of the upper surface of the fixed plate 13 parallel to the first reinforcing rib 14. A third reinforcing rib 16 is arranged between the first reinforcing rib 14 and the second reinforcing rib 15. A fourth reinforcing rib 17 and a fifth reinforcing rib 18 are arranged vertically on the lower surface of the fixed plate 13. This design can make the connection structure of the fixed plate 13 and the upper intake pipe 1 more stable and durable.

[0035] At least one partition plate 19 is vertically arranged inside the upper intake pipe 1. The partition plate 19 can divide the airflow into multiple small parts when the airflow enters the upper intake pipe 1, thereby reducing the airflow speed and the noise generated by the airflow.

[0036] The upper air inlet pipe 1 is provided with a groove 15, and a sealing gasket is arranged in the groove 15, and a protrusion is arranged on the sealing gasket, so that the stability of the connection of the upper air inlet pipe 1 is ensured, and the sealing performance is improved.

[0037] As Figure 5 When the air quality outside is good, the operator controls the actuator 7, the drive shaft 5 rotates, drives the baffle 4 to rotate, blocks the air inlet 8, the upper air inlet pipe 1 is opened, so that the gas flows into through the upper air inlet pipe 1; Figure 6 When the air quality outside is poor or it is raining and snowing, the operator controls the actuator 7, the drive shaft 5 rotates, drives the baffle 4 to rotate, blocks the upper air inlet pipe 1, the upper air inlet pipe 1 is closed, so that the gas flows into from the air inlet 8, since the air inlet 8 is in the vehicle interior, the gas is all the air in the cabin interior, so that the rain and snow are blocked from entering the air filter. The specific embodiments described in the present text are only illustrative of the spirit of the present application; those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
