[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The purpose of the present invention is to provide an air intake duct and a vehicle to solve the problems existing in the prior art. By arranging a first side air intake port and a bottom air intake port on the air intake duct, the air intake mode of the air intake duct can be changed, which not only has stronger applicability, but also can prevent rainwater from entering the engine through the first side air intake port of the air intake duct and damaging the engine.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Embodiment 1:

[0033] like Figure 1 to Figure 6 As shown, this embodiment discloses an air intake duct, including a top air intake section 1 and a bottom air intake section 2 which are connected. After being installed on a vehicle, the top air intake section 1 is located at the top of the cab, and the bottom air intake section 2 is located at the back of the cab. In order to facilitate the fixing of the top air intake section 1 and the bottom air intake section 2, the top air intake section 1 and the bottom air intake section 2 are connected in an L shape in this embodiment. In this embodiment, a first side air intake port 3 opened in a side direction (the vehicle travel direction is forward) is provided on the top air intake section 1, and a side air intake shielding mounting portion for fixing a side air intake shielding member is provided at the first side air intake port 3; a bottom air intake port 4 opened downward is also provided on the top air intake section 1, and a bottom air intake shielding mounting portion for fixing a bottom air intake shielding member is provided at the bottom air intake port 4; an exhaust port 5 for connecting to the engine air intake end is provided on the bottom air intake section 2.

[0034] When in use, the first side air inlet 3 and the bottom air inlet 4 can both be in an open state, and the air inlet duct can take in air from the side and the bottom. When the vehicle is operating in heavy rain or other conditions with obvious lateral water inflow, for vehicles with high requirements for rain protection, the side air inlet shielding mounting portion is used to connect the side air inlet shielding component to shield the first side air inlet 3 to prevent spray water from entering the engine from the first side air inlet 3 and damaging the engine, and the air inlet duct takes in air from the bottom air inlet 4 to supply the engine on the vehicle. When operating in an environment without obvious lateral water inflow, if the air intake of the first side air inlet 3 is sufficient to supply the engine, or for a vehicle type that requires lateral air intake, the bottom air inlet 4 can be shielded by connecting the bottom air inlet shielding component through the bottom air inlet shielding mounting portion.

[0035] Therefore, this embodiment can change the air intake method of the air intake duct by arranging the first side air intake port 3 and the bottom air intake port 4 on the air intake duct. It is not only suitable for vehicles with different air intake types and has stronger applicability, but also can meet the needs of vehicles with higher requirements for rain protection, ensure the air intake quality, and prevent rainwater from entering the engine through the first side air intake port 3 of the air intake duct and damaging the engine.

[0036] In this embodiment, the side air intake shielding mounting portion includes a side fixing hole for connecting bolts, the side fixing hole can be an internal threaded hole or a through hole, and the side air intake shielding member is fixed by the bolts connected to the side fixing holes. The bottom air intake shielding mounting portion includes a bottom fixing hole for connecting bolts, the bottom fixing hole can be an internal threaded hole or a through hole, and the bottom air intake shielding member is fixed by the bolts connected to the bottom fixing hole. Specifically, the side fixing hole and the bottom fixing hole can be directly opened on the air intake duct, or a fixing ear plate can be set at the air inlet corresponding to the air intake duct, and the side fixing hole and the bottom fixing hole are set on the fixing ear plate. The setting method of the side fixing hole and the bottom fixing hole is not shown in the figure in this embodiment. The side air intake shielding member and the bottom air intake shielding member can both be shielding plates adapted to the shape of the corresponding air inlet.

[0037] Of course, in this embodiment, other structures may also be used to connect the side air intake shielding components or the bottom air intake shielding components, such as a snap-fit ​​structure.

[0038] Along the driving direction of the vehicle, the first side air inlet 3 gradually tilts outward from front to back, so that the first side air inlet 3 has a projection surface facing forward. When the vehicle is driving, the first side air inlet 3 is easier to inhale air, thereby increasing the air intake amount of the first side air inlet 3.

[0039] In this embodiment, the top of the top air intake section 1 has an upward bulge 6. The bulge 6 makes the top air intake section 1 have a larger volume, which can increase the maximum air intake volume; on the other hand, when some vehicle application scenarios require the first side air intake 3 and the bottom air intake 4 to be opened at the same time, this bulge 6 can play a buffering role to avoid serious turbulence between the bottom air intake and the side air intake in the flat cavity, thereby increasing the air intake resistance. In order to reduce the air resistance when the vehicle is moving, the front end of the air intake duct and the front end of the bulge 6 in this embodiment are both streamlined.

[0040] In order to improve the strength of the raised portion 6 , a plurality of reinforcing ribs 20 are provided on the raised portion 6 in this embodiment.

[0041] In this embodiment, a side air intake grille 7 is provided at the first side air intake port 3, and the side grille pieces in the side air intake grille 7 are arranged vertically, and along the driving direction of the vehicle, the side grille pieces gradually tilt outward from front to back; a bottom air intake grille 8 is provided at the bottom air intake port 4, and the bottom grille pieces in the bottom air intake grille 8 are arranged horizontally, and along the driving direction of the vehicle, the bottom grille pieces gradually tilt backward from top to bottom. The side air intake grille 7 and the bottom air intake grille 8 can prevent large-volume impurities (such as leaves, shredded paper, etc.) in the air from entering the air intake duct, and at the same time, the side air intake grille 7 also has a certain rainproof effect. In this embodiment, the side air intake grille 7 and the bottom air intake grille 8 are both detachably fixed by bolts.

[0042] like Figure 4~Figure 6 As shown, in this embodiment, a rain shield 9 is provided on the inner side of the side air intake hood, and the rain shield 9 can be fixed on the air intake duct or on the side air intake hood. The two sides of the rain shield 9 are respectively provided with a second side air intake port 10 and a side air outlet 11, wherein the second side air intake port 10 is directly opposite to the first side air intake port 3. A rain shield plate 12 is also provided inside the rain shield 9, and along the driving direction of the vehicle, the rain shield plate 12 is located behind the side air outlet 11; as an embodiment, the rain shield plate 12 is arranged to tilt backward from the outside to the inside along the air intake direction, and such an arrangement is to cooperate with the arrangement structure of the side grille sheet in the side air intake grille 7 to achieve a better rain shielding effect.

[0043] In this embodiment, the rain shield 9 also includes a top air outlet 13 connected to the inside of the top air inlet section 1, and the top air outlet 13 and the side air outlet 11 can take in air at the same time. As one embodiment, a side air outlet shielding mounting portion for fixing the side air outlet shielding member is provided at the side air outlet 11. The side air outlet shielding mounting portion is a fixing hole, and the side air outlet shielding member can be a shielding plate. When the top air outlet 13 can meet the air intake of the engine or in a rainy environment, the side air outlet 11 can be blocked by a shielding plate, which can further prevent rainwater from entering the engine from the air intake duct.

[0044] As an embodiment, the bottom plate 14 in the rain shield 9 is tilted, and the end of the bottom plate 14 where the side air outlet 11 is located is higher than the end where the second side air inlet 10 is located. Along the driving direction of the vehicle, the rear end of the bottom plate 14 is higher than the front end, so as to prevent rainwater on the bottom plate 14 from flowing into the air inlet. A rain collecting trough 15 is provided on the outer edge of the bottom plate 14, and a drain port 16 is provided at the front end of the rain collecting trough 15, so that the blocked rainwater can flow out along the rain collecting trough 15.

[0045] Embodiment 2:

[0046] This embodiment discloses a vehicle, including a cab and an air intake duct as described above, wherein a top air intake section 1 in the air intake duct is installed on the top of the cab, and the top air intake section 1 has a mounting ear 17 for installation, and the mounting ear 17 has a top mounting hole 18, and after installation, an air intake gap is provided between the bottom air intake port 4 and the upper surface of the cab; and a bottom air intake section 2 in the air intake duct is installed on the back of the cab. The bottom air intake section 2 has a side mounting hole 19 for installation.

[0047] Adaptive changes made according to actual needs are all within the protection scope of the present invention.
