Specifically, referring to fig. 1 and 2, this gas pipe 101 includes a first conveying portion 1011 and a second conveying portion 1012; the first conveying part 1011 is communicated with an air filter of a vehicle and used for conveying filtered gas into the air filter and filtering the gas again to ensure that the gas entering the cylinder is pure and the combustion efficiency of the cylinder is ensured; the waterproof structure 102 includes a waterproof housing 1021 and an air inlet 1022, the waterproof housing 1021 is connected to the second conveying portion 1012, and the air inlet 1022 is opened at an end of the waterproof housing 1021 far from the second conveying portion 1012, so as to introduce the external air into the waterproof housing 1021.

Wherein, the gas pipe 101 can be integrally injection molded or assembled; in this embodiment, the gas pipe 101 is integrally injection molded, so that the manufacturing cost is lower, and gas leakage is avoided.

In addition, the air pipe 101 is fixedly connected with the waterproof structure 102, and the following embodiments can be included:

alternatively, the waterproof case 1021 and the second conveying part 1012 can be detachably connected by a snap, a bolt or a rivet, so as to be convenient for replacing and repairing the waterproof case; in addition, the waterproof casing 1021 and the second conveying part 1012 can be integrally formed or welded to be connected into a whole, so that the sealing performance is better.

For example, referring to fig. 2, in the gravity direction, a protruding ridge plate 1013 is provided on the outer wall of the pipe of the gas pipe 101, and in the gravity direction, the ridge plate 1013 is respectively located at the upper and lower sides of the gas pipe 101, and is connected to the waterproof housing 1021 by the ridge plate 1013 in a snap-fit manner; in addition, the second conveying part 1012 may adopt a half pipe structure, and the waterproof housing 1021 is connected in contact with the second conveying part 1012; specifically, the waterproof housing 1021 is provided with a clamping groove corresponding to the ridge plate 1013, the ridge plate 1013 is clamped in the clamping groove, and the edge of the waterproof housing 1021 is tightly attached to the edge of the pipeline of the second conveying part 1012, so that the gas in the waterproof housing 1021 is prevented from leaking to the outside, and the whole air inflow is ensured. The outer side plate 10212 of the waterproof shell 1021 is also provided with an arc-shaped groove matched with the pipeline of the gas pipe 101; the second conveying part 1012 is communicated with the first conveying part 1011 through a communicating pipeline, a half pipeline of the second conveying part 1012 is connected with a part of communicating pipeline, the waterproof shell 1021 is connected with the communicating pipeline, and the waterproof shell 1021 is positioned at the opposite side of the second conveying part 1012, so that the waterproof shell 1021 is tightly connected with the gas conveying pipe 101, gas leakage is avoided, and combustion efficiency is guaranteed.

It should be noted that, the second conveying part 1012 may not adopt a half-pipe structure, that is, the second conveying part 1012 is connected to the waterproof housing 1021 in an inserting manner.

Further, the following embodiments may be adopted for the waterproof case 1021:

referring to fig. 2, the waterproof case 1021 includes a back plate 10211 and a peripheral side plate 10212, the peripheral side plate 10212 surrounds an outer frame of the waterproof case 1021, the outer frame may be square, oval, or other polygonal shapes, and the specific shape is not limited.

Wherein, curb plate 10212 includes the upper half portion and the lower half portion that arrange in proper order in the direction of gravity, and backplate 10211 is located the lower half portion of curb plate 10212, and backplate 10211 encloses into air current via hole 10213 with the upper half portion of curb plate 10212.

Specifically, referring to fig. 2, a side plate 10212 of a circle is disposed around a back plate 10211, and an air flow hole 10213 is disposed at one end of the back plate 10211 close to the second conveying portion 1012, and when the waterproof housing 1021 is connected to the second conveying portion 1012, the air flow hole 10213 is communicated with a pipeline in the second conveying portion 1012, so as to introduce air into the air pipe 101.

It should be noted that the side plate 10212 and the back plate 10211 may be integrally formed or assembled.

In addition, the air flow holes 10213 are rectangular, and the length direction thereof is the same as the length direction of the back plate 10211, as shown in fig. 2; so that more gas enters the gas delivery conduit 101 and so that gas entry into the gas delivery conduit 101 is also facilitated.

Specifically, an orthographic projection of the gas flow aperture 10213 on a reference plane perpendicular to the gas entry direction does not overlap with an orthographic projection of the gas inlet 1022 on the reference plane.

It should be noted that the reference plane perpendicular to the gas inlet direction may be the reference plane of the back plate 10211 in fig. 2.

Further, the orthographic projection of the air flow through hole 10213 and the orthographic projection of the air inlet 1022 are sequentially arranged in the gravity direction, that is, the orthographic projection of the air flow through hole 10213 is above the orthographic projection of the air inlet 1022, that is, the air flow through hole 10213 and the air inlet 1022 are not on the same horizontal plane, and the position of the air flow through hole 10213 is higher than the position of the air inlet 1022.

It should be noted that when air mixed with rain, snow, liquid or sundries enters the waterproof housing 1021, since the height of the air flow hole 10213 is higher than the air inlet height of the air inlet 1022, the mixed air first contacts with the back plate 10211, and then is guided and shunted by the back plate 10211, during the air climbing upwards, the mixed air cannot climb into the air flow hole 10213 due to the gravity influence of the rain, snow, liquid or sundries themselves, so that the rain, snow, liquid or sundries entrained in the air are separated at the connection between the back plate 10211 and the side plate 10212; the separated gas continuously flows upwards along the back plate 10211, then enters the second conveying part 1012 through the gas flow through hole 10213, and then sequentially enters the air filter and the engine, so that sundries are prevented from entering the air filter to be impacted and attached to the filter element, and the filtering performance of the filter element is further ensured; in addition, rain, snow, liquid and the like are prevented from entering the engine, the dynamic property of the engine and the stability of the engine are guaranteed, and the safety of the vehicle is improved.

For the sake of understanding, the gas enters in the direction of the coordinate system X in fig. 2, and the direction opposite to the direction of the coordinate system Z in fig. 2 is the direction of gravity.

Further, as shown in fig. 2, in order to better separate the gas entering into the waterproof housing 1021, a partition plate 1023 is provided at the junction of the back plate 10211 and the gas flow through hole 10213, and the partition plate 1023 extends in a direction away from the second conveying part 1012; also, to further ensure that rain, snow, liquid, and debris do not enter the air delivery duct 101, the orthographic projection of the partition 1023 on a reference plane perpendicular to the air intake direction is located above the orthographic projection of the air intake 1022 on the reference plane, and does not overlap with each other.

It should be noted that the width of the partition 1023 can be smaller than the side plate 10212 of the waterproof housing 1021 to ensure that the gas can smoothly climb up and enter the gas pipe 101.

Alternatively, referring to fig. 2, the partition 1023 has a circular arc shape, and the partition 1023 protrudes downward in the gravity direction, that is, the inward curved surface of the partition 1023 faces the second conveying part 1012 and the outward curved surface faces the side plate 10212; the air enters the waterproof shell 1021 and contacts with the back plate 10211, at this time, rain, snow, liquid and sundries in the air are blocked by the arc-shaped partition plates 1023, so that the rain, snow, liquid and sundries can be further prevented from flowing into the air conveying pipe 101, the filtering effect of the air filter is guaranteed, and the running stability of a vehicle is guaranteed. In addition, the arc-shaped partition plate 1023 is adopted, which can reduce the resistance of the gas passing through the partition plate 1023 and ensure the fluidity of the gas.

It should be noted that, when the partition 1023 is of an arc-shaped structure, the orthographic projection of the highest point of the partition 1023 on the reference plane is higher than the orthographic projection of the air inlet 1022 on the reference plane, so as to better block rain, snow, liquid or sundries in the air and avoid affecting the filtering effect of the air filter.

Alternatively, the partition 1023 may be a flat straight plate structure, i.e., the partition 1023 and the back plate 10211 are perpendicular to each other and extend away from the second conveying part 1012; an inclined plate structure may be adopted, that is, the partition plates 1023 and the back plate 10211 have a certain inclination angle, and the partition plates 1023 are inclined upward to ensure the filtering effect on rain, snow, liquid and sundries. In addition, the length of the partition plate 1023 should be the same as the distance of the opposite side plates 10212 of the waterproof case 1021 to better ensure the blocking of rain, snow, liquid and sundries.

It should be noted that the vertical height of the partition plate 1023 from the side plate 10212 is at least 1.5 times the height of the air inlet 1022 in the vertical direction, so as to ensure the separation effect of rain and snow, liquid and sundries, improve the filtering effect of the air cleaner, and ensure the stability of the vehicle.

Further, in order to clean the separated rain, snow, liquid and sundries in time, at least one drainage hole 1024 is formed at the connection position of the back plate 10211 and the side plate 10212 in the gravity direction, as shown in fig. 3.

For example, the drain holes 1024 may have one or more structures such as a circle, a square, an oval, or a diamond; optionally, when the drain hole 1024 is a square hole, it is more convenient to drain rain, snow, accumulated water and sundries; in addition, the water discharge holes 1024 are formed at the connection between the rear plate 10211 and the side plate 10212, which is beneficial to discharging sundries, rain, snow and accumulated water.

Further, referring to fig. 2 or 3, three drain holes 1024 are provided, and three drain holes 1024 are provided as square holes having the same size, so as to facilitate the integral injection molding with the waterproof housing 1021.

Further, referring to fig. 2 or fig. 4, the back plate 10211 is further provided with a plurality of guide plates 1025 for shunting the gas entering the waterproof housing 1021, and in the gravity direction, one end of each guide plate 1025 is connected to the outer arc surface of the partition plate 1023, the other end is connected to the side plate 10212 opposite to the partition plate 1023, and the guide plates 1025 are perpendicular to the side plates 10212 and the back plate 10211, and the length of the guide plates 1025 in the gas entering direction may be smaller than the length of the side plates 10212, or may be the same as the length of the side plates 10212, so as to ensure stable shunting of the gas, and better filter the gas.

In addition, the orthographic projection of the guide plate 1025 on the horizontal reference plane can be overlapped with the orthographic projection of the partition plate 1023 on the horizontal reference plane, namely the lengths of the guide plate 1025 and the partition plate 1023 in the X direction can be the same, and the flow stability of the gas is ensured; of course, the orthographic projection of the baffle 1025 on the horizontal reference plane may also be non-overlapping with the orthographic projection of the baffle 1023 on the horizontal reference plane.

It should be understood that the horizontal reference plane is the plane in which side panel 10212 lies.

It should be noted that, the guide plate 1025 can be integrally formed with the partition plate 1023 and the side plate 10212, or can be assembled and fixedly connected with the partition plate 1023 and the side plate 10212; in addition, the drain holes 1024 and the guide plates 1025 are arranged at intervals in the length direction of the partition plate 1023, namely, one drain hole 1024 is arranged between the two guide plates 1025, and one guide plate 1025 is arranged between the two drain holes 1024, so that the gas after being shunted can be better cleaned.

Further, referring to fig. 2 or 4, in order to eliminate an angle between the guide plate 1025 and the back plate 10211 and effectively prevent accumulation of impurities, rain, snow and liquid, the thickness of the guide plate 1025 is gradually increased in the air intake direction of the air, i.e., the cross-section of the guide plate 1025 is "herringbone".

It should be noted that the thickness direction of the baffle 1025 is perpendicular to the air intake direction and also perpendicular to the gravity direction, i.e., the Y direction in fig. 2.

Further, the waterproof case 1021, the partition plate 1023, and the guide plate 1025 can be made of the same material; optionally, waterproof housing 1021, partition 1023, and baffle 1025 are nylon material; in addition, the waterproof casing 1021, the partition plate 1023 and the guide plate 1025 are integrally injection molded to ensure the stability of the whole structure, avoid gas leakage and reduce the manufacturing cost; it should be understood that when waterproof housing 1021, partition 1023, and baffle 1025 are integrally injection molded, drain holes 1024 are also formed during the injection molding process.

Further, referring to fig. 1, 2 and 4, the waterproof structure 102 further includes an air intake housing 1026, one end of the air intake housing 1026 is provided with the air inlet 1022 for air intake, and the other end of the air intake housing 1026 is detachably connected to one end of the waterproof housing 1021 far away from the second conveying portion 1012.

Exemplarily, a plurality of holes are formed in the outer side plate 10212 of the air inlet housing 1026, a buckle is arranged on the end face of the side plate 10212, opposite to the air inlet housing 1026, of the waterproof housing 1021, the buckle is clamped in the holes, the waterproof housing 1021 and the air inlet housing 1026 are fixedly connected into a whole, and fixing and dismounting are more convenient by adopting a clamping and clamping mode of the buckle.

Of course, the air intake housing 1026 and the waterproof housing 1021 may be detachably connected by bolts or rivets, so as to facilitate maintenance and replacement.

Further, as shown in fig. 1 and fig. 2, the air intake housing 1026 adopts an "L" type structure, the area of the air inlet 1022 of the air intake housing 1026 is smaller than the area of the outlet of the air intake housing 1026, and the position of the air inlet 1022 is provided with the foreign matter prevention grille 103, so as to prevent large foreign matters from entering the air cleaner and protect the filtering effect of the air cleaner.

Illustratively, the foreign matter prevention grid 103 has a plurality of openings with the same size, and the plurality of openings are connected with each other for blocking foreign matters with larger diameters.

The foreign matter prevention grille 103 and the air intake housing 1026 adopt different connection modes, and specifically include the following embodiments:
