[0026] As shown in Figure 1 and 2 , a heavy truck front mask assembly, comprising a mask body 1 and a cover plate 2 connected to each other, the mask body 1 is provided with a mounting port 101, the cover plate 2 is arranged inside the mounting port 101, and the cover plate 2 is connected with the mask body 1 through an elastic connecting piece; the cover plate 2 is provided with a plurality of evenly distributed ventilation holes 201, and the back surface of the cover plate 2 is provided with a plurality of baffles 5, the number of the baffles 5 is equal to and corresponds to the number of the ventilation holes 201, the baffles 5 and the ventilation holes 201 are arranged opposite to each other, and there is a gap between the baffles 5 and the ventilation holes 201.

[0027] The above-mentioned front mask assembly is suitable for but not limited to heavy trucks. During the driving process of the vehicle, external air enters the vehicle interior through the ventilation holes 201 to support the normal operation of the vehicle. When it is raining, a large amount of rainwater enters the ventilation holes 201 together with the air. At this time, under the blocking action of the baffles 5, the flow rate of the airflow is slowed down, so that the rainwater mixed in the airflow falls downward under the action of gravity or inertia, realizing the separation of water in the airflow. After that, the airflow enters the vehicle interior, reducing the water content in the airflow and reducing the probability of vehicle failure caused by excessive water intake.

[0028] The arrangement of the baffles 5 can also change the flow direction of the airflow entering from the ventilation holes 201, expand the distribution range and uniformity of the airflow, and improve the air intake effect of the vehicle. The elastic connecting piece elastically connects the cover plate 2 and the mask body 1, so that when the cover plate 2 is impacted by a large object, the elastic connection can play a buffering role, thereby reducing the probability of damage to the cover plate 2 and prolonging the service life of the mask assembly.

[0029] Further improvement is as shown in Figure 2 , 3As shown in FIGS. 5, the inner side of the mounting opening 101 is provided with a flange 102 in the circumferential direction, the elastic connecting piece includes a sliding rod 103 fixedly connected with the flange 102, a sliding sleeve 203 fixedly connected with the cover plate 2, and a spring 4 sleeved on the sliding rod 103, the sliding rod 103 is in sliding fit with the sliding rod 103, and the two ends of the spring 4 are connected with the flange 102 and the cover plate 2 respectively. Specifically, the axial line direction of the sliding rod 103 is consistent with the advancing direction of the vehicle, and a plurality of sliding rods 103 are distributed at equal intervals along the extension direction of the flange 102, the cover plate 2 is supported by the plurality of sliding rods 103, the firmness of the installation of the cover plate 2 is improved, the cover plate 2 is limited by the mounting opening 101, and the firmness of the installation of the cover plate 2 in the inner side of the mounting opening 101 is further improved; when the cover plate 2 is impacted, the sliding rod 103 and the sliding sleeve 203 in mutual sliding fit enable the cover plate 2 to slide forward and backward along the sliding rod 103, and under the buffering action of the spring 4, part of the impact force borne by the cover plate 2 is released, so that the impact borne by the cover plate 2 is reduced, the probability of damage of the cover plate 2 is reduced, and the failure rate of the mask assembly is reduced.

[0030] Further improvement is that, as shown in FIGS. 5, the end of the sliding rod 103 is fixedly connected with the flange 102, and the front end of the sliding rod 103 is threadedly connected with an end cover 6. Specifically, the sliding rod 103 is provided with a threaded section at the front end, the end cover 6 has an internal thread for threadedly connecting with the threaded section, the disassembly and assembly of the end cover 6 can facilitate the disassembly and assembly between the cover plate 2 and the sliding rod 103, the convenience of disassembly and assembly of the cover plate 2 is improved, and the convenience of vehicle maintenance is improved.

Specifically, the sliding rod 103 is provided with a threaded section at the front end, the end cover 6 has an internal thread for threadedly connecting with the threaded section, the disassembly and assembly of the end cover 6 can facilitate the disassembly and assembly between the cover plate 2 and the sliding rod 103, the convenience of disassembly and assembly of the cover plate 2 is improved, and the convenience of vehicle maintenance is improved. Figure 2 4 Further improvement is that, as shown in FIGS. 5, the end of the sliding rod 103 is fixedly connected with the flange 102, and the front end of the sliding rod 103 is threadedly connected with an end cover 6. Specifically, the sliding rod 103 is provided with a threaded section at the front end, the end cover 6 has an internal thread for threadedly connecting with the threaded section, the disassembly and assembly of the end cover 6 can facilitate the disassembly and assembly between the cover plate 2 and the sliding rod 103, the convenience of disassembly and assembly of the cover plate 2 is improved, and the convenience of vehicle maintenance is improved.

[0032] Further improvement is that, as shown in FIGS. 5, the end of the sliding rod 103 is fixedly connected with the flange 102, and the front end of the sliding rod 103 is threadedly connected with an end cover 6.

Figure 5 6 ​​​As shown, the baffle 5 and the cover plate 2 are detachably connected; specifically, the inner side of the baffle 5 is integrally formed with a connecting sleeve 202, the number of connecting sleeves 202 and the ventilation holes 201 are equal and correspond one-to-one, the connecting sleeves 202 and the ventilation holes 201 are coaxially arranged, the baffle 5 is fixedly connected with a fixing ring 502 by a fixing rod 503, and the inner circumferential surface of the fixing ring 502 and the outer circumferential surface of the connecting sleeve 202 are provided with matching threads. The connection between the threaded sleeve 202 and the retaining ring 502 facilitates the installation and removal of the baffle 5 and the cover plate 2. This makes the installation of the baffle 5 convenient. In seasons with less rain, the baffle 5 can be partially removed, and the air intake speed of the vehicle can be controlled by adjusting the setting of the baffle 5. At the same time, the retaining ring 502 can be twisted to move it along the axial direction of the connecting sleeve 202, thereby controlling the gap between the baffle 5 and the connecting sleeve 202 to control the air intake of the ventilation hole 201. The air intake of the ventilation hole 201 can be manually adjusted according to different temperatures, thereby ensuring the normal operation of the vehicle and reducing the vehicle failure rate.

[0033] Further improvements include, for example Figure 5 As shown, adjacent baffles 5 are spaced apart. Sufficient spacing between adjacent baffles 5 allows airflow to pass through, ensuring that enough air enters the vehicle interior.

[0034] Further improvements include, for example Figure 5 As shown, the orthographic projection of the ventilation hole 201 onto the baffle 5 falls within the area of ​​the baffle 5. This ensures that the baffle 5 effectively blocks the ventilation hole 201, preventing airflow carrying water from passing through one side of the baffle 5, thereby ensuring effective water removal, reducing the amount of water entering the vehicle interior, and lowering the vehicle's failure rate.

[0035] Further improvements include, for example Figure 6 As shown, a conical guide block 501 is provided on the side of the baffle 5 near the ventilation hole 201. The guide block 501 can guide the flow direction of the airflow, so that the airflow smoothly changes from flowing along the axial direction of the ventilation hole 201 to flowing in a direction parallel to the baffle 5, and can diffuse the airflow to the periphery of the baffle 5; it can not only reduce the force of the airflow on the baffle 5, thereby reducing the probability of the baffle 5 being damaged due to excessive force, but also make the airflow evenly distributed around the baffle 5, improving the airflow intake range and uniformity; and it can also reduce the splashing caused by water hitting the baffle 5, so that the water can flow smoothly along the outer periphery of the guide block 501 and the surface of the baffle 5, and finally fall to the bottom of the mounting port 101, and be discharged from the gap between the cover plate 2 and the mask body 1.
