[0031] Next, refer to Figures 1 - 4 Describe the air-conditioning air inlet assembly 100 according to an embodiment of the present utility model. The air-conditioning air inlet assembly 100 can effectively prevent foreign objects such as rainwater from entering the interior of the air-conditioning system and the cab, ensure sufficient air circulation inside and outside the vehicle, thereby improving the operating efficiency and lifespan of the air conditioner and enhancing the riding comfort of passengers.

[0032] As Figures 1 - 4 shown, the air-conditioning air inlet assembly 100 according to an embodiment of the present utility model includes: a water trough sheet metal 1 and an air inlet cover plate 2.

[0033] The water trough sheet metal 1 is mainly used to drain the rainwater flowing onto the vehicle body to the outside of the vehicle, prevent the water flow from entering the interior of the vehicle body and the interior of the vehicle body sheet metal structure, thereby protecting the internal components of the vehicle from rust and damage, keeping the interior of the vehicle dry, and providing a comfortable riding environment for passengers.

[0034] The water trough sheet metal 1 is formed with an air inlet 11 for the air conditioner. That is to say, the water trough sheet metal 1 is formed with an opening for the air intake of the air conditioning system. In this way, the external air can enter the air conditioning system through the air inlet 11 for the air conditioner, enabling the air circulation between the inside of the vehicle and the outside world, thereby adjusting the temperature inside the vehicle and improving the riding comfort of passengers. Thus, the water trough sheet metal 1 can achieve the dual functions of drainage and ventilation.

[0035] The air inlet cover plate 2 is used to cover above the air inlet 11 for the air conditioner to prevent external dust, foreign objects, etc. from entering the inside of the air conditioning system and affecting the normal operation of the air conditioning system. Among them, the air inlet cover plate 2 is installed at the air inlet 11 for the air conditioner, that is, the shape and size of the air inlet cover plate 2 are adapted to those of the air inlet 11 for the air conditioner, so that the air inlet cover plate 2 can be installed and covered on the air inlet 11 for the air conditioner, completely covering the air inlet 11 for the air conditioner, thereby protecting the air inlet 11 for the air conditioner. And the air inlet cover plate 2 is formed with air inlet grille holes 21 distributed in multiple rows and columns. The air inlet grille holes 21 are communicated with the air inlet 11 for the air conditioner. In other words, a plurality of regularly arranged air inlet grille holes 21 are opened on the air inlet cover plate 2, and the external air can enter the air inlet 11 for the air conditioner through the multiple air inlet grille holes 21 on the air inlet cover plate 2, and then enter the inside of the air conditioning system. At the same time, the air inlet grille holes 21 distributed in multiple rows and columns can achieve a more uniform air flow distribution, ensure sufficient fluidity of the air flow, improve the air intake efficiency, and the smaller air inlet grille holes 21 can prevent foreign objects such as fallen leaves from entering the inside of the cab. Thus, through the design of the air inlet grille holes 21 in multiple rows and columns on the air inlet cover plate 2, the air flow can enter the air conditioning system more evenly and efficiently, improving the efficiency and performance of the air conditioning system.

[0036] And the air inlet cover plate 2 is in sealing fit with the circumferential edge of the air inlet 11 for the air conditioner, that is, there is no gap at the connection of the circumferential edge of the air inlet cover plate 2 and the air inlet 11 for the air conditioner, and the two are closely fitted and connected, so as to prevent external dust, rainwater, cleaning liquid, etc. from entering the inside of the air conditioner and the inside of the cab, improving the airtightness and energy efficiency ratio of the air conditioning system and the riding comfort of passengers.

[0037] For the air inlet assembly 100 according to the embodiment of the present invention, by providing the air inlet 11 for the air conditioner on the water trough sheet metal 1 and sealingly fitting the air inlet cover plate 2 with the circumferential edge of the air inlet 11 for the air conditioner, it can effectively prevent external rainwater and other foreign objects from entering the inside of the air conditioning system and the inside of the cab, and the air inlet grille holes 21 distributed in multiple rows and columns provided on the air inlet cover plate 2 can ensure sufficient air circulation between the inside and outside of the vehicle while blocking external foreign objects, thereby improving the operating efficiency and service life of the air conditioning system and enhancing the riding comfort of passengers.

[0038] In some embodiments, the air inlet cover plate 2 includes an upper plate portion 22, a lower plate portion 23, and two side plate portions 24. The upper plate portion 22 is located above the lower plate portion 23 and is spaced apart from the lower plate portion 23 and distributed oppositely. The two side plate portions 24 are spaced apart and are respectively connected between the upper plate portion 22 and the lower plate portion 23 to jointly define an air inlet grille hole 21.

[0039] Specifically, as Figure 2 shown, both the upper plate portion 22 and the lower plate portion 23 of the air inlet cover plate 2 extend forward, and are spaced apart in the up-down direction. The upper plate portion 22 is located above and is the upper boundary of the air inlet grille hole 21, and the lower plate portion 23 is located below and is the lower boundary of the air inlet grille hole 21. The two side plate portions 24 are connected between the upper plate portion 22 and the lower plate portion 23 to form a side boundary, thereby jointly defining the air inlet grille hole 21 with the upper plate portion 22 and the lower plate portion 23, which is beneficial to the flow of air. At the same time, the design of the four plate portions can protect the air inlet grille hole 21, resist rainwater, and prevent rainwater and the like from entering the air conditioner air inlet 11 through the air inlet grille hole 21.

[0040] In practice, threaded through holes can be provided around the air inlet cover plate 2, and corresponding threaded through holes are provided on the water trough sheet metal 1. Thus, the air inlet cover plate 2 and the water trough sheet metal 1 can be fixedly connected by nuts and stud welding studs, increasing the connection reliability and stability between the two, preventing the air inlet cover plate 2 from falling off and affecting the air intake effect of the air conditioner air inlet 11.

[0041] In some embodiments, both the upper plate portion 22 and the lower plate portion 23 are configured to extend obliquely downward from top to bottom in the front-rear direction, and the air inlet grille hole 21 penetrates obliquely downward from top to bottom in the front-rear direction.

[0042] Specifically, as Figure 2 shown, both the upper plate portion 22 and the lower plate portion 23 extend obliquely downward from top to bottom in the front-rear direction. The inclined setting can prevent rainwater, dust, etc. from accumulating at the air inlet cover plate 2, thereby preventing rainwater from entering the air conditioner air inlet 11. Moreover, the extension length of the upper plate portion 22 is greater than that of the lower plate portion 23, so that the upper plate portion 22 can shield the air inlet grille hole 21 from top to bottom to prevent rainwater flowing down from the upper plate portion 22 from entering the air inlet grille hole 21, and the inclined lower plate portion 23 can prevent rainwater accumulated on the water trough sheet metal 1 from entering the air inlet grille hole 21, thus effectively protecting the air conditioner system from the influence of external rainwater and preventing internal components from rusting.

[0043] And the inclined upper plate portion 22 and lower plate portion 23 can make the air inlet grille hole 21 penetrate obliquely downward from top to bottom in the front-rear direction. Thus, through the inclined air inlet grille hole 21, it can be ensured that the air flow can enter the air conditioner air inlet 11 more smoothly, improving the ventilation efficiency.

[0044] In some embodiments, a first shielding flange 221 is provided at the upper side edge of the upper plate portion 22. The first shielding flange 221 bends and extends forward and upward relative to the upper plate portion 22, and / or a second shielding flange 231 is provided at the lower side edge of the lower plate portion 23. The second shielding flange 231 bends and extends forward relative to the lower plate portion 23.

[0045] Specifically, as Figure 2 shown, a first shielding flange 221 is formed by bending and extending forward and upward at the upper side edge of the upper plate portion 22. The setting of the first shielding flange 221 can prevent rainwater from flowing into the air intake grille hole 21 along the inner wall of the front panel upper plate 3 and then into the cab. Moreover, a second shielding flange 231 is formed by bending and extending forward at the lower side edge of the lower plate portion 23. The setting of the second shielding flange 231 can block the water accumulated on the water trough sheet metal 1 from entering the air intake grille hole 21 and then into the cab.

[0046] In some embodiments, the width of the first shielding flange 221 is L1, and it satisfies: L1≥8mm. That is, the width L1 of the first shielding flange 221 can be set to other values such as 8mm, 8.5mm, 10mm, etc., as long as the width L1 is greater than or equal to 8mm.

[0047] By setting the width L1 of the first shielding flange 221 to be greater than or equal to 8mm, the effect of the first shielding flange 221 in shielding rainwater can be greatly improved, and rainwater can be prevented from flowing into the air intake grille hole 21 along the inner wall of the front panel upper plate 3. It can be understood that the narrower the width L1 of the first shielding flange 221, the worse the rainwater shielding effect. Similarly, the wider the width L1 of the first shielding flange 221, the better the rainwater shielding effect, but it should not be too wide to avoid interference with the front panel upper plate 3.

[0048] And / or, the height difference between the second shielding flange 231 and the inner groove bottom surface of the water trough sheet metal 1 is L2, and it satisfies: L2≥50mm. That is to say, the distance between the second shielding flange 231 and the inner groove bottom surface of the water trough sheet metal 1 is L2. L2 can be set to other values such as 50mm, 50.6mm, 55mm, etc., as long as the height difference L2 is greater than or equal to 50mm.

[0049] By setting the height difference L2 between the second shielding flange 231 and the inner groove bottom surface of the water chute sheet metal 1 to be greater than or equal to 50 mm, the distance safety between the second shielding flange 231 and the inner groove bottom surface of the water chute sheet metal 1 can be ensured, thereby effectively preventing the rainwater accumulated at the bottom of the water chute sheet metal 1 from flowing back into the air intake grille holes 21, and further flowing back into the interior of the air conditioning system and the cab interior, affecting the normal operation of the air conditioning system. It can be understood that the larger the height difference L2 between the second shielding flange 231 and the inner groove bottom surface of the water chute sheet metal 1 is set, the larger the distance between the second shielding flange 231 and the inner groove bottom surface of the water chute sheet metal 1 is, thereby greatly improving the effect of shielding rainwater, but it cannot be too large to affect the setting of the air intake grille holes 21.

[0050] In some embodiments, a sealing ring platform 25 is formed on the circumference of the air inlet cover plate 2, and a sealing member 26 is clamped between the circumferential edge of the sealing ring platform 25 and the circumferential edge of the air conditioning air inlet 11.

[0051] Specifically, as Figure 2 and Figure 4 shown, a protruding sealing ring platform 25 is provided on the circumferential circle of the air inlet cover plate 2, and a sealing member 26 is clamped between the circumferential edge of the sealing ring platform 25 and the circumferential edge of the air conditioning air inlet 11, that is, the sealing ring platform 25 is used to support and install the sealing member 26. When actually installing the air inlet cover plate 2, the sealing member 26 is pressed between the sealing ring platform 25 and the air conditioning air inlet 11, and both the sealing member 26 and the sealing ring platform 25 are adapted to the shape and size of the air conditioning air inlet 11, so that the sealing member 26 can be tightly pressed between the air inlet cover plate 2 and the air conditioning air inlet 11, realizing the sealing of the air conditioning air inlet 11, thereby effectively preventing foreign objects such as rainwater from entering the interior of the air conditioning system through the gap between the air inlet cover plate 2 and the air conditioning air inlet 11, affecting the operation of the air conditioning system, and effectively sealing the periphery of the air conditioning air inlet 11 through the sealing member 26, and can also ensure that the air flow all enters the air conditioning air inlet 11 from the air intake grille holes 21, preventing air leakage, thereby ensuring the stable flow of the air flow.

[0052] And the setting of the sealing ring platform 25 and the sealing member 26 can also improve the installation stability of the air inlet cover plate 2, ensure that it can maintain a fixed position under various working conditions, and prevent the air inlet cover plate 2 from falling off.

[0053] In some embodiments, the sealing ring platform 25 forms a sealing groove, the sealing groove opens towards the water chute sheet metal 1, and the sealing member 26 is installed in the sealing groove.

[0054] As Figure 2As shown, the sealing ring platform 25 is formed with a sealing groove which faces the water trough sheet metal 1 and is open, facilitating the installation of the seal 26 around the air inlet 11 of the air conditioner. The shape and size of the sealing groove are adapted to those of the seal 26, so that the seal 26 can be stably installed in the sealing groove, more closely connected to the sealing ring platform 25, further improving the sealing performance and preventing the seal 26 from shifting to affect the sealing effect.

[0055] And / or, the width of the seal 26 is L3, and it satisfies: 9mm ≤ L3 ≤ 11mm, that is, the width L3 of the seal 26 can be set to 9mm, 10mm, 11mm or other values, as long as 9mm ≤ L3 ≤ 11mm is satisfied.

[0056] Thus, by setting the width L3 of the seal 26 within this range, while ensuring the sealing performance, the air inlet cover 2 can be stably and reliably installed on the water trough sheet metal 1. In actual design, the seal 26 can use a closed-cell foam with a width of 10mm, and it can interfere with the water trough sheet metal 1 by 2mm during installation. Since the internal bubbles of the closed-cell foam are independent and closed, without interconnected channels, it has the characteristics of moderate elasticity, rapid shape recovery, non-absorbency, waterproofness, etc. Therefore, through the good waterproof and airtight performance of the closed-cell foam, the effective sealing of the air inlet 11 of the air conditioner can be achieved, preventing rainwater from flowing into the air inlet 11 of the air conditioner, and thus achieving the best sealing effect.

[0057] And as Figure 4 shown, in practice, the seal 26 can partially overlap on the side of the air inlet cover 2. The upper seal 26 can be set outside the lower seal 26, and the overlap amount can be set to ≥10mm to ensure sufficient sealing at the connection of the seal 26.

[0058] In some embodiments, as Figure 2 shown, the water trough sheet metal 1 includes a horizontal plate portion 12 and an inclined plate portion 13. The inclined plate portion 13 is connected to the rear side edge of the horizontal plate portion 12 and extends upward obliquely from front to back relative to the horizontal plate portion 12. The air inlet 11 of the air conditioner is formed at the inclined plate portion 13, and the air inlet cover 2 is connected to the front side of the inclined plate portion 13.

[0059] Thus, by setting the air inlet 11 of the air conditioner at the inclined inclined plate portion 13, the inclined plate portion 13 can guide the rainwater to flow down, prevent the rainwater from accumulating and entering the air conditioner interior from the air inlet cover 2, and is conducive to setting the inclined air inlet grille holes 21 to improve the air intake efficiency. And connecting the air inlet cover 2 to the front side of the inclined plate portion 13 is conducive to the installation and disassembly of the air inlet cover 2 and the maintenance of the air inlet 11 of the air conditioner, greatly improving the operation convenience.

[0060] In some embodiments, the width of each air inlet grille hole 21 in the horizontal direction is L4, and it satisfies: 11 mm ≤ L4 ≤ 14 mm. That is, the width L4 of each air inlet grille hole 21 in the horizontal direction can be set to 11 mm, 12.5 mm, 13 mm or other values, as long as 11 mm ≤ L4 ≤ 14 mm is satisfied.

[0061] And / or, the width of each air inlet grille hole 21 in the up and down direction is L5, and it satisfies: 11 mm ≤ L5 ≤ 14 mm. The width L5 of each air inlet grille hole 21 in the up and down direction can be set to 11 mm, 12.5 mm, 13 mm or other values, as long as 11 mm ≤ L4 ≤ 14 mm is satisfied.

[0062] Thus, by setting the width L4 of each air inlet grille hole 21 in the horizontal direction and the width L5 of each air inlet grille hole 21 in the up and down direction within a reasonable range, while the air inlet grille holes 21 can block foreign objects from the outside, a certain ventilation volume can be ensured, and it is avoided that the size of the air inlet grille holes 21 is too large or too small, which affects the air intake effect of the air inlet cover 2, thereby affecting the efficient operation of the air conditioning system.

[0063] In actual design, the overall size area of the air inlet grille holes 21 can be designed to be greater than 1.5 times the air intake area of the air conditioning blower. Thus, the number of the air inlet grille holes 21 can be set more, the opening area is larger, the blower can inhale air more easily, the air intake resistance is reduced, thereby improving the air intake efficiency, ensuring sufficient air intake volume. At the same time, the noise and vibration generated during air flow can be reduced, and the width L4 of each air inlet grille hole 21 in the horizontal direction and the width L5 of each air inlet grille hole 21 in the up and down direction can both be set to 12.5 mm to achieve the best air intake effect and ensure the full circulation of air inside and outside the cab.

[0064] The present utility model also proposes a vehicle.

[0065] The vehicle according to the embodiment of the present utility model is provided with the air conditioning air inlet assembly 100 of any one of the above embodiments.

[0066] Through the design of the seal 26, the seal ring platform 25, the first shielding flange 221, the second shielding flange 231, and the reasonable size design, water flow in all directions can be blocked from entering the cab interior, effectively ensuring the normal operation of the air conditioning system.

[0067] Among them, by providing an air inlet for the air conditioner 11 on the sheet metal of the water chute 1 and sealingly mating the air inlet cover plate 2 with the circumferential edge of the air inlet for the air conditioner 11, it is possible to effectively prevent foreign matters such as rainwater from the outside from entering the interior of the air conditioning system and the cab. Moreover, the air inlet grille holes 21 arranged in multiple rows and columns on the air inlet cover plate 2 can block foreign matters from the outside while ensuring sufficient air circulation inside and outside the vehicle, thereby improving the operating efficiency and lifespan of the air conditioning system, enhancing the riding comfort of passengers, and further improving the reliability of the vehicle.
