[0035] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0036] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0037] The first embodiment of the utility model provides a ventilation cover structure, such as Figure 1-Figure 3 As shown, the ventilation cover structure includes a ventilation cover 1, and the top of the ventilation cover 1 is provided with a first water baffle 2 and a second water baffle 3 in sequence from the rear to the front of the vehicle body. The first water baffle 2, the second water baffle 3 and the ventilation cover 1 form a drainage groove 4. The first water baffle 2 is provided with a plurality of drainage holes 5. The bottom of the drainage groove 4 is provided with a drainage port 6 connected to a drainage pipe 8. The bottom of the drainage groove 4 is also provided with a step structure 7 so that rainwater entering the drainage groove 4 from the drainage holes 5 flows to the drainage port 6.

[0038] The first water baffle 2, the second water baffle 3 and the ventilation cover 1 form a drainage trough 4 which is closed on all sides and open on the top. Rainwater enters the drainage trough 4 through the drainage hole 5 on the first water baffle 2, enters the drainage pipe 8 through the drainage port 6 at the bottom of the drainage trough 4, and then flows out of the vehicle through the drainage pipe 8. The step structure 7 provided at the bottom of the drainage trough 4 forms areas of different heights at the bottom of the drainage trough 4, and rainwater can flow quickly along one side of the step structure 7 to the other side of the step structure 7. Specifically, rainwater flows along the area with a higher height to the area with a lower height, and then flows to the drainage port 6, and is discharged out of the vehicle through the drainage pipe 8. By providing the step structure 7 at the bottom of the drainage trough 4, the drainage efficiency can be improved, and the phenomenon of rainwater gathering at the bottom of the drainage trough 4 can be avoided.

[0039] Specifically, the drain ports 6 are arranged at both ends of the drain groove 4 to ensure the drainage capacity of the drain groove 4. The drain pipe 8 connected to the drain ports 6 can guide the water flow to be discharged along the set path to prevent the water flow from flowing uncontrolled in the engine compartment and causing damage to the components in the engine compartment.

[0040] like Figure 4 As shown, a guide portion 9 is provided on the top of the ventilation cover 1, and the guide portion 9 is located at the rear side of the first water baffle 2. The guide portion 9 is inclined downward toward the first water baffle 2 and extends to the bottom of the first water baffle 2. The guide portion 9 can be set as a multi-stage structure, gradually extending to the bottom of the first water baffle 2. Rainwater on the front windshield flows to the bottom of the windshield under the action of gravity, and then flows into the drainage groove 4 along the guide portion 9 on the ventilation cover 1. The guide portion 9 is set to be inclined downward toward the first water baffle 2. Compared with the rear structure of the first water baffle 2 being set as a straight structure, it is more conducive to the flow of rainwater, increases the flow speed of rainwater, and improves the water guide efficiency of the ventilation cover structure.

[0041] In some embodiments, the sizes of the plurality of drainage holes 5 are different. The drainage holes 5 are set to different sizes according to the flow rate of rainwater, so that rainwater is not easily gathered at the rear side of the first water baffle plate 2 when flowing through the first water baffle plate 2, and rainwater flows smoothly into the drainage groove 4.

[0042] Specifically, Figure 5 As shown, a wiper mounting hole 10 for mounting a windshield wiper is provided on the ventilation cover 1. Since the wiper mounting hole 10 is provided on the ventilation cover 1, the amount of water in the surrounding area will be larger during the operation of the wiper. Near the wiper mounting hole 10, the amount of water required to pass through the drainage hole 5 is larger. Therefore, the drainage hole 5 designed on the first water baffle 2 includes a first drainage hole 51 and a second drainage hole 52. According to the wiping direction of the wiper, the first drainage hole 51 is designed to be large in size near the wiper mounting hole, and the other parts are designed to be small in size. Second drainage holes 52 are designed to facilitate rainwater to flow quickly into the drainage groove 4.

[0043] The second drainage holes 52 are tooth-shaped drainage holes 5 arranged along the length direction of the first water baffle 2. The second drainage holes 52 are arranged at the first water baffle 2. In the higher area of ​​the first water baffle 2, multiple rows of second drainage holes 52 can be set, and in the lower area of ​​the first water baffle 2, one row of second drainage holes 52 can be set. According to the different heights of the first water baffle 2 along the length direction, different numbers of drainage holes 5 are set to reasonably utilize the space of the first water baffle 2 and improve the flow efficiency of rainwater. At the same time, the second drainage holes 52 can filter the water flowing to the drain port 6, and block most of the impurities behind the first water baffle 2, so as to avoid blockage at the drain port 6 and make the drainage groove 4 ineffective.

[0044] In some embodiments, Figure 3 , Figure 5 and Figure 6 As shown, the step structure 7 includes a water retaining rib 71, and the water retaining rib 71 extends from the bottom of the guide part 9 to the second water retaining plate 3 along the front-rear direction of the vehicle body. The front-rear direction of the vehicle body refers to the direction of travel of the vehicle, that is, the vehicle X direction. Taking the setting of a water retaining rib 71 as an example for explanation, the two ends of the water retaining rib 71 are respectively connected to the bottom of the guide part 9 and the second water retaining plate 3, dividing the drainage groove 4 into two areas with different heights. Rainwater flows along the guide part 9 to the water retaining rib 71, and flows along the side with a lower height under the action of gravity. Rainwater is not easy to gather at the bottom of the drainage groove 4, so that all the water in the drainage groove 4 flows out. In other embodiments, the number of water retaining ribs 71 is not limited, and multiple water retaining ribs 71 can be provided. Multiple water retaining ribs 71 form a stepped structure with different heights, which further improves the discharge speed of water in the drainage groove 4 and ensures that there is no water residue in the drainage groove 4.

[0045] Specifically, the amount of rainwater near the wiper mounting hole 10 is large, so the water retaining rib 71 is arranged near the wiper mounting hole 10. The water retaining rib 71 passes through the first drainage hole 51 and extends to the second water retaining plate 3. The first drainage hole 51 plays a role of avoidance, providing layout space for the water retaining rib 71.

[0046] In some embodiments, Figure 5 As shown, the step structure 7 also includes an inclined portion 72 that is inclined downward toward the drain outlet 6 along the left-right direction of the vehicle body. The left-right direction of the vehicle body refers to the Y direction of the vehicle. The inclined portion 72 is provided at a position close to the drain outlet 6. The inclined portion 72 and other positions of the drain groove 4 have a height difference. Specifically, the height of the inclined portion 72 is lower than the height of the water retaining rib 71, which is conducive to the rainwater in the drain groove 4 flowing along the inclined portion 72 to the drain outlet 6 and being discharged outside the vehicle, further improving the discharge efficiency of rainwater.

[0047] In some embodiments, the first water retaining plate 2 includes a first plate portion 21 and a second plate portion 22 connected up and down, the second plate portion 22 is located above the first plate portion 21, the hardness of the second plate portion 22 is less than the hardness of the first plate portion 21, and the drainage hole 5 is provided in the first plate portion 21; the second water retaining plate 3 includes a third plate portion 31 and a fourth plate portion 32 connected up and down, the fourth plate portion 32 is located above the third plate portion 31, and the hardness of the fourth plate portion 32 is less than the hardness of the third plate portion 31. The first plate portion 21 and the third plate portion 31 are made of hard rubber material, which is convenient for connection with the ventilation cover plate 1, ensuring the supporting strength and rigidity, and ensuring the water retaining performance. The second plate portion 22 and the fourth plate portion 32 are made of soft rubber material to avoid scratching pedestrians and have a more beautiful appearance.

[0048] like Figure 6 and Figure 7 As shown, in some embodiments, the front side of the ventilation cover 1 is snapped with the vehicle body through the buckle 11 and fixed by the fastener 12, the rear side of the ventilation cover 1 is connected to the upper side of the front windshield lower cross beam 100, and the lower side of the front windshield lower cross beam 100 is connected to the front panel 200. The front side of the ventilation cover 1 is directly connected to the vehicle body without using a mounting frame to install the ventilation cover 1 on the vehicle body, and the front windshield lower cross beam 100 and the front panel 200 do not need to be connected through other parts (such as air chamber plates), thereby reducing the number of parts and achieving lightweight of the entire vehicle.

[0049] like Figure 1 As shown, a positioning arm 13 is provided on the side of the drain pipe 8, and a positioning groove 14 is provided on the edge of the ventilation cover 1. The positioning arm 13 and the positioning groove 14 are connected to the vehicle body after matching. The drain pipe 8 is connected to the vehicle body through the positioning arm 13, rather than the drain pipe 8 being connected only to the ventilation cover 1, which increases the installation points of the drain pipe 8 and improves the structural stability of the drain pipe 8. When a large flow of water flows through the drain pipe 8, the drain pipe 8 can also maintain a stable state and is not easy to fall off. In addition, a positioning groove 14 matching the positioning arm 13 is provided on the ventilation cover 1 to limit the drain pipe 8.

[0050] The second embodiment of the present invention provides a vehicle, comprising the above-mentioned ventilation cover plate structure. The vehicle corresponds to the ventilation cover plate structure of the above-mentioned embodiment, and any optional items in the ventilation cover plate structure embodiment are also applicable to the vehicle embodiment, which will not be repeated here.
