Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 8, a vent flap assembly according to the present invention will now be described. The vent flap assembly comprises a vent flap 1 and a water guide shroud 16. The ventilation cover plate 1 is provided with a ventilation hole 15, the water guide shield 16 is arranged below the ventilation hole 15, a water guide groove 18 for bearing water flow flowing through the ventilation hole is formed in the water guide shield 16, and a water guide opening 19 for communicating with the space outside the vehicle is formed in the water guide groove 18.

It is to be understood that the term "upper" used for indicating the direction refers to a direction away from the ground when the vehicle is placed on the ground, and for the vent flap 1, the side of the vent flap 1 facing away from the ground is the upper side of itself, and the term "lower" used for indicating the direction indicates a direction opposite to "upper", which is a direction toward the ground.

Compared with the prior art, the ventilation cover plate assembly provided by the invention is provided with the water guide shield 16 below the ventilation cover plate 1, the water flow passing through the ventilation hole 15 completely flows into the water guide shield 16, the water flow is prevented from splashing into the cabin, and the water flow is discharged out of the vehicle through the water guide opening 19 under the guide of the water guide groove 18. The water guide shield 16 is arranged, so that the condition that water leaks into the cabin through the ventilation hole 15 is avoided, the area of the ventilation hole 15 can be increased when the ventilation hole 15 is designed, and the air inlet volume of the air conditioner can be increased.

The water guide opening 19 is a structure capable of guiding water flow out of the water guide chute 18, and may be an opening structure provided in a chute wall or an opening structure provided in another position.

Optionally, the area of the water chute 18 is larger than that of the vent hole 15, and the water guiding shield 16 is attached to the lower surface of the vent cover plate 1 to ensure that all water flowing through the vent hole 15 can be received.

As a specific implementation of the embodiment of the present invention, please refer to fig. 1 to 8, the vent holes 15 are mesh holes. The mesh structure who rivers have the reposition of redundant personnel effect, the rivers of avoiding flowing through ventilation hole 15 are too big to lead to water to spill over or spill water guide guard shield 16, and consequently, the area covered in ventilation hole 15 can be bigger, and then makes the air conditioner air input more sufficient.

Referring to fig. 2 to 8, as an embodiment of the present invention, the ventilation holes 15 are respectively disposed at two ends of the ventilation flap 1, and the water guiding shields 16 are correspondingly disposed at lower sides of two ends of the ventilation flap 1. The water flow directly passes through the flow channel water guide shields 16 at the two end parts of the ventilation cover plate 1, the internal space of the engine room is reasonably utilized, the water guide path is shortened, the water flow splashes into the engine room in an effective mode, and the water inflow of the engine room is avoided. The two water guide shrouds 16 at both ends are substantially the same in structure, and the specific structure may be changed adaptively according to the internal structure of the vehicle.
