The connecting protrusion 24 is embedded in the connecting groove 34 to restrict the airflow at the connection between the first housing 2 and the second housing 3, thereby improving the sealing performance of the first housing 2 and the second housing 3 at the connection.
[0038] Please combine Figure 5 In one example, the main body 11 is bent and extended from the ends of the first side plate 22 and the second side plate 32 to form a first connecting plate 23 and a second connecting plate 33, respectively. Optionally, the first connecting plate 23 and the second connecting plate 33 are perpendicular to the first connecting plate 23 and the second connecting plate 33, respectively. The first connecting plate 23 protrudes from its surface in a direction close to the second connecting plate 33 to form a connecting protrusion 24. The portion of the second connecting plate 33 corresponding to the connecting protrusion 24 is recessed relative to the other portion to form a connecting groove 34. The connecting protrusion 24 is embedded in the connecting groove 34, which can improve the sealing performance and connection strength.

The snap-fit portion 27 snaps into the snap-fit groove 351 to fix the first housing 2 and the second housing 3 together. Specifically, the snap-fit portion 27 is block-shaped, plate-shaped, or hook-shaped, etc. In this example, the main body 11 is preferably made of an elastic material such as plastic.
[0040] Optionally, the first housing 2 and the second housing 3 are respectively provided with abutting fixing plate 28 and snap-fit plate 35. The fixing plate 28 protrudes from its surface near the snap-fit plate 35 to form a snap-fit part 27, and a snap-fit groove 351 is formed in the snap-fit plate 35.
[0041] Specifically, a portion of the first side plate 22 is formed as a fixing plate 28, or the fixing plate 28 is integrally connected to the surface of the first side plate 22. The second side plate 32 protrudes from one end away from the second main plate 31 to form a snap-fit plate 35, or a portion of the second side plate 32 is formed as the snap-fit plate 35. A snap-fit groove 351 is formed in the snap-fit plate 35.
[0042] Optionally, the snap-fit portion 27 is flat, and its projection along the extension direction of the main body 11 is approximately trapezoidal, meaning the width of the snap-fit portion 27 gradually decreases away from the fixing plate 28. Specifically, the snap-fit portion 27 includes a top surface and two side surfaces. The top surface is parallel to the first side plate 22, and the two side surfaces extend obliquely from opposite ends of the top surface toward the first side plate 22. During installation, the snap-fit plate 35 abuts against the side surfaces of the snap-fit portion 27. The oblique arrangement of the side surfaces relative to the top surface facilitates guiding the relative movement of the snap-fit plate 35 and the snap-fit portion 27, making installation convenient.
[0043] Optionally, one of the first housing 2 and the second housing 3 is provided with a guide portion 29, and the other is provided with a guide groove 37. The guide portion 29 is embedded in the guide groove 37. The guide portion 29 is preferably block-shaped, plate-shaped or column-shaped, and is used to guide the movement direction of the first housing 2 and the second housing 3 relative to each other during installation.
[0044] In one example, the first side plate 22 is provided with a plurality of snap-fit portions 27 along the extension direction of the main body 11, and a guide portion 29 is provided between two adjacent snap-fit portions 27. Optionally, the first housing 2 protrudes from the outer surface of its first side plate 22 to form a guide portion 29, the guide portion 29 including at least two opposing guide plates, the distance between the two guide plates gradually increasing in the direction away from the second housing 3, which is beneficial for guiding the movement direction of the first housing 2 and the second housing 3 relative to each other during installation, further facilitating installation.
[0045] Please see Figure 8In one example, the main body 11 is provided with a mounting plate 25. The mounting plate 25 and the front frame 5 are respectively provided with a first mounting hole 252 and a second mounting hole 54 for fasteners to pass through. The mounting plate 25 is fixedly connected to the front frame 5 by fasteners. Optionally, the first side plate 22 protrudes from its outer surface to form the mounting plate 25. In this example, the fastener is a bolt, and the second mounting hole 54 is a threaded hole, or a nut is pre-embedded in the second mounting hole 54 by means of riveting or other methods. The main body 11 is fixedly connected to the frame beam 51 by bolts, which facilitates installation and maintenance and helps to improve the connection stability.
[0046] Optionally, one of the mounting plate 25 and the front frame 5 is provided with a positioning post 26, and the other is provided with a positioning hole 55. Specifically, the mounting plate 25 extends vertically from the surface near the frame beam 51 to form the positioning post 26, and the frame beam 51 has a positioning hole 55 near the second mounting hole 54.

During installation, the positioning post 26 passes through the positioning hole 55 to guide the movement direction of the air intake shroud 1 relative to the frame beam 51, further facilitating installation.
[0047] Please see Figure 7 Optionally, the main body 11 is provided with a first reinforcing rib 251 and a second reinforcing rib 253, wherein the first reinforcing rib 251 is connected between the main body 11 and the mounting plate 25, and a plurality of second reinforcing ribs 253 are provided around the first mounting hole 252, which can improve the structural strength of the connection.
[0048] Please see Figure 6 In one example, the air intake shroud 1 of this invention also includes a sealing gasket 4. The sealing gasket 4 is generally a hollow rectangular frame or a "U" shape, and is made of materials such as foam, sponge, or rubber. Specifically, the sealing gasket 4 is fixedly connected to at least one of the areas corresponding to the air inlet 12 and air outlet 13 of the main body 11. The sealing gasket 4 is preferably fixedly connected to the main body 11 by means of adhesive bonding, etc., for easy installation. Optionally, there are two sealing gaskets 4.
