[0029] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0030] Reference appendix Figure 1 To appendix Figure 6 As shown, the present application provides an air intake system for an air conditioner, including:

[0031] The front windshield 1, the front windshield 1 includes a lower end and a higher end;

[0032] The engine compartment cover 2 is arranged at the lower end of the front windshield 1, and there is an air intake gap 4 between the engine compartment cover 2 and the front windshield 1;

[0033] The ventilation cover 3 is installed at the lower end of the front windshield 1 and is located below the engine compartment cover 2, forming a circulation space 6 with the engine compartment cover 2; a water baffle 5 is arranged on the ventilation cover 3, and the water baffle 5 divides the circulation space 6 into a first area 601 and a second area 602 which are arranged side by side and communicated; the ventilation cover 3 is provided with a drain port 301 in the first area 601, the ventilation cover 3 is provided with a drain channel 702 and an air intake grille 7 in the second area 602, a water trough 8 is arranged on the ventilation cover 3 below the air intake grille 7, and an air intake port 801 for the air conditioner is arranged on the water trough 8;

[0034] Along the air intake direction of the air conditioner, the air intake gap 4, the first area 601, the second area 602, the air intake grille 7 and the water trough 8 are distributed in sequence. The engine compartment cover 2 is provided with a convex part 201 for separating water in the second area 602, and the convex part 201 protrudes into the second area 602.

[0035] It should be noted that the setting of the air intake gap 4 is to realize the air intake of the air conditioner, and the air intake position is set below the front windshield 1 to facilitate the entry of fresh air. The setting of the ventilation cover 3 is to prevent rainwater from entering the vehicle. The setting of the water baffle 5 is to block the water in the air intake and reduce the amount of water entering the second area 602. The setting of the air intake grille 7 is to filter the entering air and so on. The setting of the water trough 8 is to further separate water and air and reduce the possibility of water flowing out from the air intake port 801 of the air conditioner. The setting of the convex part 201 is to block the moisture, so that when the air passes through the convex part 201, the moisture is blocked and drops into the second area 602 and flows out through the drain channel 702, reducing the amount of water entering the water trough 8. The setting of the drain channel 702 is to realize the outflow of the water in the second area 602.

[0036] When the air conditioner is inhaled, the air enters the first area 601 from the air intake gap 4, then goes over the water baffle 5 to the second area 602, then enters the water flow groove 8 from the air intake grille 7, and goes out from the air intake port 801. If the incoming air contains water (such as rainy days), the water will enter the air intake gap 4 along the front windshield 1, then enter the first area 601, and be discharged through the drainage port 301 in the first area 601. After the air carries part of the water over the water baffle 5 to the second area 602, the water is blocked by the convex portion 201 and falls into the second area 602, and flows out from the drainage channel 702.

[0037] In this embodiment, the water retaining plate 5, the convex portion 201, etc. can prevent water from entering the water flow channel 8, thereby reducing the risk of water entering the air-conditioning intake system.

[0038] Exemplarily, the water trough 8 is made of plastic to meet the requirement of lightweight.

[0039] In an exemplary embodiment, a flow gap 501 is provided between the water retaining plate 5 and the cabin cover 2 , and the flow gap 501 communicates the first area 601 and the second area 602 .

[0040] It should be noted that the flow gap 501 is provided to connect the first area 601 and the second area 602 .

[0041] In an exemplary embodiment, the height of the middle portion of the water baffle 5 is lower than the heights of both ends, and the air intake grille 7 is disposed at one end of the water baffle 5 .

[0042] In this embodiment, since the heights of the two ends of the water baffle plate 5 are higher than the height of the middle part of the water baffle plate 5, most of the water and gas enter the second area 602 through the middle part of the water baffle plate 5. In order to prevent water from directly entering the air intake grille 7 after passing over the middle part of the water baffle plate 5, the air intake grille 7 is arranged away from the middle part of the water baffle plate 5, that is, the air intake grille 7 is arranged at the end of the water baffle plate 5.

[0043] It should be noted that, since the middle height of the water baffle 5 is lower than the heights of the two ends of the water baffle 5 , the flow gap 501 between the middle of the water baffle 5 and the cabin cover 2 is larger than the flow gap 501 between the two ends of the water baffle 5 and the cabin cover 2 .

[0044] Exemplarily, the flow gap 501 between the middle of the water retaining plate 5 and the cabin cover 2 can be 10-15 mm, and the flow gap 501 between the two ends of the water retaining plate 5 and the cabin cover 2 can be 4-6 mm. The specific size of the flow gap 501 can be set according to needs.

[0045] Exemplarily, the flow gap 501 between the middle of the water baffle 5 and the engine cover 2 is 10 mm, 11 mm, 12 mm, 13 mm, 14 mm or 15 mm. The flow gaps 501 between the two ends of the water baffle 5 and the engine cover 2 are 4 mm, 5 mm or 6 mm.

[0046] In an exemplary embodiment, the flow path from the flow gap 501 to the intake grille is for the air intake of the air conditioner, and the convex portion 201 is provided on the flow path.

[0047] It should be noted that as long as the convex portion 201 is provided on the flow path between the flow gap 501 and the intake grille, it can play a role in making the moisture carried in the intake air fall. The setting of the convex portion 201 advances the landing point of the water entrained in the air from the existing air grille to the position of the convex portion 201, effectively reducing the amount of water entering the air grille.

[0048] Exemplarily, the intake grille 7 is composed of evenly distributed hexagonal holes. On the premise of meeting the intake requirements, the shape of the holes is not limited, and ribs or rib plates for structural strengthening can be provided below it.

[0049] Exemplarily, the convex portion 201 is provided corresponding to the middle flow gap 501 of the water baffle 5, that is, beside the middle flow gap 501 of the water baffle 5, so as to increase the water blocking performance of the convex portion 201.

[0050] Exemplarily, two or more convex portions 201 can be provided to increase the water blocking effect.

[0051] In an exemplary embodiment, the ventilation cover 3 forms a first diversion groove 302 in the first area 601, and the drain port 301 is provided at both ends of the first diversion groove 302; the ventilation cover 3 forms a second diversion groove 303 in the second area 602, the second diversion groove 303 is arranged side by side with the first diversion groove 302, and the intake grille 7 is arranged in the second diversion groove 303.

[0052] In this embodiment, the first diversion groove 302 and the second diversion groove 303 are provided to correspondingly lead out the water entering the first area 601 and the second area 602.

[0053] It should be noted that the water baffle 5 is arranged between the first diversion groove 302 and the second diversion groove 303 to achieve separation.

[0054] Exemplarily, the bottoms of the first diversion groove 302 and the second diversion groove 303 can be set as a plane or an inclined plane inclined towards the water outlet direction to meet different requirements.

[0055] In an exemplary embodiment, a water-blocking boss 701 is arranged around the air intake grille 7, and a drainage channel 702 is formed between the water-blocking boss 701 and the inner side surface of the second diversion groove 303.

[0056] It should be noted that the water-blocking boss 701 is provided to prevent the water entering the second area 602 from flowing directly into the air intake grille 7 along the bottom of the second diversion groove 303, thereby reducing the possibility of water ingress.

[0057] Exemplarily, the water-blocking boss 701 and the air intake grille 7 are integrated, and a sealing ring is arranged between the water-blocking boss 701 and the bottom of the second diversion groove 303 to reduce the possibility of water ingress into the water flow groove 8.

[0058] In an exemplary embodiment, an arc-shaped diversion surface 802 is formed on the bottom of the water flow groove 8 from high to low. The high end of the arc-shaped diversion surface 802 is connected to the ventilation cover plate 3, and the air conditioner air intake 801 is arranged at the low end of the arc-shaped diversion surface 802.

[0059] In this embodiment, the arc-shaped diversion surface 802 is arranged from high to low to achieve the diversion effect on the water flow, while the gas can pass above the arc-shaped diversion surface 802 and go out from the air conditioner air intake 801.

[0060] In an exemplary embodiment, a drainage groove 804 is further recessed downward between the arc-shaped diversion surface 802 and the air conditioner air intake 801. The highest position of the drainage groove 804 is lower than the lowest position of the air conditioner air intake 801, and a water outlet is arranged in the drainage groove 804.

[0061] It should be noted that in order to prevent the water on the arc-shaped diversion surface 802 from going out through the air intake, a drainage groove 804 is arranged between the arc-shaped diversion surface 802 and the air conditioner air intake 801. The water flowing down along the arc-shaped diversion surface 802 flows into the drainage groove 804 and is discharged from the water outlet 805. The drainage groove 804 is recessed to facilitate the water to fall under the action of gravity and flow along the drainage groove 804 to the water outlet 805 for discharge.

[0062] Exemplarily, in order to prevent the intake of engine room exhaust gas, a shielding cover plate is arranged on the water outlet 805. The shielding cover plate is hinged to the water outlet 805. When there is accumulated water in the water outlet 805,

[0063] Exemplarily, an arc-shaped surface 803 is formed on the top of the water flow groove 8 from low to high. The low end of the arc-shaped surface 803 is connected to the ventilation cover plate 3, and the air conditioner air intake 801 is arranged at the high end of the arc-shaped surface 803. The setting of the arc-shaped surface 803 plays a role in guiding the gas. Compared with being set as a plane, when the gas passes through the arc-shaped surface 803, the water carried in the air can be blocked and condensed and fall onto the arc-shaped diversion surface 802.

[0064] It should also be noted that, compared with setting a stepped surface inside the water chute 8, the stepped surface is more likely to cause water accumulation and affect the drainage of water when the arc-shaped diversion surface 802 and the arc-shaped surface 803 are set.

[0065] It is worth emphasizing that in this solution, the water chute 8 as a whole presents a tubular structure. The water chute 8 realizes the diversion function through the arc-shaped diversion surface 802 and the arc-shaped surface 803, realizes the function of dripping water carried in the air through the arc-shaped surface 803, and realizes the drainage of water in the water chute 8 through the drainage groove 804 and the water outlet. Compared with the prior art of increasing the internal space height of the water chute 8 and using gravity to separate water and gas, this solution can effectively reduce the internal space height of the water chute 8, reduce the overall occupied volume of the water chute 8, and at the same time can achieve a good separation effect of water and gas.

[0066] In an exemplary embodiment, a drainage groove 806 is recessed downward on the arc-shaped diversion surface 802, and the drainage groove 806 is arranged from the high end to the low end of the arc-shaped diversion surface 802.

[0067] In this embodiment, the setting of the drainage groove 806 is to realize the water flow diversion, further realize the separation of water and gas, and reduce the possibility of water flowing out of the air inlet 801 of the air conditioner.

[0068] In addition, the present application also provides a vehicle, including the above-mentioned automotive air-conditioning intake system.

[0069] In this embodiment, setting the automotive air-conditioning intake system of the present application on the vehicle can effectively reduce the amount of water entering the vehicle from the air inlet 801 of the air conditioner.

[0070] The above embodiments only illustrate the principles and effects of the present invention by way of example, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
