[0042] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] like Figures 1-5 As shown, this utility model provides an external circulation air duct module, including an air duct housing 1 and a guide body 2. The air duct housing 1 has a through-flow duct, one end of which is an air duct inlet, and the top of the through-flow duct is an air duct top wall 11. The guide body 2 is disposed at the air duct inlet of the through-flow duct and connected to the air duct top wall 11. The guide body 2 has a guide groove, the opening of which faces away from the air duct housing 1. The guide groove extends at least partially along the extension direction of the top edge of the air duct inlet and has an outlet.

[0044] In this invention, a guide fluid 2 is provided at the air duct inlet of the air duct housing 1, and a guide groove is provided on the guide fluid 2. The guide groove extends along the extension direction of the top edge of the air duct inlet and is provided with an outlet. This allows rainwater and other liquids flowing down the water dam along the ventilation panel 100 to be guided and concentrated out during operation, preventing rainwater and other liquids from being directly sucked into the air conditioning unit 200 by the air conditioner, thus improving safety and reliability.

[0045] In this embodiment, the duct housing 1 includes a top wall 11, a bottom wall 12, and two side walls 13. The top wall 11 and the bottom wall 12 are spaced apart, and the two side walls 13 are located between the top wall 11 and the bottom wall 12. The top wall 11, the bottom wall 12, and the two side walls 13 form a through-flow duct. One end of the through-flow duct is the duct inlet. The extension direction of the through-flow duct is the length direction of the top wall 11, the bottom wall 12, and the two side walls 13. At one end of the through-flow duct, the width sides of the top wall 11, the bottom wall 12, and the two side walls 13 form the duct inlet. That is, the guide channel extends at least partly along the width direction of the top wall 11. Liquid flowing from the outlet into the through-flow duct flows out through the drain on the bottom wall 12 or the side wall 13, or is drawn out from the through-flow duct through a conduit.

[0046] Specifically, each end of the guide channel has an outlet. This design allows rainwater and other liquids flowing down the ventilated panel 100 to be guided through the guide channel to the left and right sides for discharge.

[0047] More specifically, the guide fluid 2 includes a first guide strip 21 and a second guide strip 22 connected to each other. The first guide strip 21 is connected to the top wall 11 of the air duct, and the second guide strip 22 is connected to the side wall 13 of the air duct. A guide groove is disposed on the first guide strip 21 and the second guide strip 22. The above arrangement allows the guide groove to receive and guide the fluid falling into the air duct from the top wall 11 and the side wall 13 of the air duct.

[0048] More specifically, the flow guide includes a first flow guide 211 and a second flow guide 221. The first flow guide 211 is disposed on the first flow guide strip 21 and extends along the length of the first flow guide strip 21. The second flow guide 221 is disposed on the second flow guide strip 22 and extends along the length of the second flow guide strip 22. One end of the second flow guide 221 is connected to the first flow guide 211, and the other end is provided with an outlet. This arrangement allows rainwater and other liquids flowing down the dam along the ventilation panel 100 to flow towards the side wall 13 of the air duct, and then along the side wall 13 to the bottom wall 12 of the air duct, thus more safely and reliably preventing rainwater and other liquids from being directly sucked into the air conditioning unit 200 by the air conditioner.

[0049] More specifically, the guide fluid 2 includes two second guide strips 22, which are located at both ends of the first guide strip 21 and are connected to the two side walls 13 of the air duct in a one-to-one correspondence. The first guide strip 21 extends along the width direction of the top wall 11 of the air duct, and the second guide strip 22 extends along the width direction of the side wall 13 of the air duct. The first guide strip 21 and the two second guide strips 22 form a U-shaped structure, which is inverted and installed on the top of the air duct inlet.

[0050] In this embodiment, the air duct housing 1 includes an upper housing and a lower housing. The upper housing and the lower housing are assembled together to form a through air duct. The top wall 11 of the air duct is disposed on the upper housing, the bottom wall 12 of the air duct is disposed on the lower housing, and the side wall 13 of the air duct can be disposed separately on the upper housing, disposed separately on the lower housing, or partially disposed on the upper housing and partially disposed on the lower housing. The guide fluid 2 is U-shaped and integrally formed with the upper housing of the air duct housing 1.

[0051] In other embodiments, the guide fluid 2 may include only the first guide strip 21, such that the guide channel includes the first guide channel 211. In other embodiments, the guide fluid 2 may also include the first guide strip 21 and two second guide strips 22 disposed at both ends of the first guide strip 21, but the second guide strips 22 extend obliquely from the end of the first guide strip 21 toward the bottom wall 12 of the air duct, and gradually approach the side wall 13 of the air duct as they move away from the first guide strip 21. In other embodiments, the guide channel has an outlet at only one end.

[0052] Specifically, the external circulation duct module also includes side water-blocking ribs 3 and / or bottom water-blocking ribs 4. The side water-blocking ribs 3 are disposed on the side wall 13 of the duct, and the bottom water-blocking ribs 4 are disposed on the bottom wall 12 of the duct. The above arrangement can effectively prevent rainwater and other liquids from being sucked into the air conditioning unit 200 along the side wall 13 or the bottom wall 12 of the duct.

[0053] In this embodiment, the external circulation duct module includes side water-blocking ribs 3 and bottom water-blocking ribs 4. In other embodiments, the external circulation duct module may include only side water-blocking ribs 3 or bottom water-blocking ribs 4.

[0054] Specifically, the two ends of the side water-blocking rib 3 are connected to the top wall 11 and the bottom wall 12 of the air duct, respectively. This arrangement can more reliably prevent rainwater and other liquids from being sucked into the air conditioning unit 200 along the side wall 13 of the air duct.

[0055] More specifically, the side water-blocking ribs 3 are plate-shaped and inclined towards the air duct inlet. This arrangement further improves the blocking effect of the side water-blocking ribs 3 on rainwater and other liquids on the side wall 13 of the air duct.

[0056] More specifically, each duct sidewall 13 is provided with at least two side water-blocking ribs 3, and multiple side water-blocking ribs 3 on the duct sidewall 13 are arranged sequentially along the length of the duct sidewall 13. The above arrangement further ensures the blocking effect of rainwater and other liquids on the duct sidewall 13.

[0057] In this embodiment, two side water-blocking ribs 3 are provided on each air duct sidewall 13, and the two side water-blocking ribs 3 are spaced apart from each other. In other embodiments, one side water-blocking rib 3, three side water-blocking ribs 3, or more than three side water-blocking ribs 3 may also be provided on each air duct sidewall 13.

[0058] Specifically, the two ends of the bottom water-blocking rib 4 are respectively connected to the two side walls 13 of the air duct. The above configuration can more reliably prevent residual water in the air duct from rushing into the air conditioning unit 200 when the vehicle brakes suddenly.

[0059] More specifically, the bottom water-retaining rib 4 is provided with a drain outlet 41, which extends to the bottom wall 12 of the air duct and runs through both sides of the bottom water-retaining rib 4 along the extension direction of the air duct. The above arrangement allows rainwater and other liquids sucked into the back of the bottom water-retaining rib 4 by the air conditioner to be discharged smoothly.

[0060] More specifically, at least two bottom water-blocking ribs 4 are provided on the bottom wall 12 of the air duct, and multiple bottom water-blocking ribs 4 are arranged sequentially along the length of the bottom wall 12 of the air duct. The above arrangement effectively improves the blocking effect of the bottom water-blocking ribs 4.

[0061] More specifically, at least two bottom water-blocking ribs 4 include a first bottom water-blocking rib and a second bottom water-blocking rib. The first bottom water-blocking rib is located on the side of the side water-blocking rib 3 facing the air duct inlet, and the second bottom water-blocking rib is located between the two side water-blocking ribs 3. With the above arrangement, before the side water-blocking ribs 3, at the air duct inlet, the liquid blocking pressure on the air duct side wall 13 is relatively low. The first bottom water-blocking rib can first provide initial blocking of rainwater and other liquids on the bottom wall 12 of the air duct, and then the side water-blocking ribs 3 and the second bottom water-blocking rib can exchange blocking power, thus ensuring the blocking effect.

[0062] In this embodiment, two bottom water-blocking ribs 4 are provided on the bottom wall 12 of the air duct. The bottom water-blocking ribs 4 are sheet-shaped and are provided on the bottom wall 12 of the air duct. The drain outlet 41 extends from the top to the bottom of the bottom water-blocking rib 4, cutting the bottom water-blocking rib 4. Of the two bottom water-blocking ribs 4, the one closer to the air duct inlet is the first bottom water-blocking rib, and the one farther away from the air duct inlet is the second bottom water-blocking rib. The height of the first bottom water-blocking rib is less than that of the second bottom water-blocking rib. The first bottom water-blocking rib is provided with two drain outlets 41, cutting the bottom water-blocking rib 4 into three equal segments. The second bottom water-blocking rib is provided with one drain outlet 41, cutting the bottom water-blocking rib 4 into two equal segments. The drain outlets 41 on the first bottom water-blocking rib and the second bottom water-blocking rib are staggered. While ensuring the blocking effect, the rainwater and other liquids sucked to the back of the bottom water-blocking rib 4 by the air conditioner can be discharged smoothly. The first bottom water-blocking rib is located on the side of the two side water-blocking ribs 3 facing the air duct inlet, and the second bottom water-blocking rib is located between the two side water-blocking ribs 3.

[0063] In other embodiments, one bottom water-blocking rib 4, three bottom water-blocking ribs 4, or more than three bottom water-blocking ribs 4 may also be provided on the bottom wall 12 of the air duct.

[0064] Specifically, the external circulation duct module also includes an end-connection seal 5, which is disposed at one end of the duct housing 1 and surrounds the outside of the duct inlet. This arrangement ensures that the end-connection seal 5 is sandwiched between the ventilation trim panel 100 and the duct housing 1, guaranteeing the sealing performance at the end connection and preventing air leakage that could cause rainwater or other liquids to be directly drawn into the air conditioning unit 200.

[0065] In this embodiment, the termination seal 5 is made of closed-cell foam, which has higher density, strength, and insulation, and is more water-resistant and moisture-proof, making it suitable for use in external circulation duct modules. The height of the termination seal 5 must ensure a seal between the ventilation panel 100 and the external circulation duct even under extreme assembly conditions. In other embodiments, the termination seal 5 can also be made of other materials such as sponge.

[0066] Specifically, the external circulation duct module also includes a one-way valve 6, and a drain outlet is provided on the bottom wall 12 of the duct. The through-ventilation duct is connected to the outside of the duct housing 1 through the drain outlet, and the one-way valve 6 is located at the drain outlet. The above configuration allows rainwater and other liquids in the through-ventilation duct to be discharged in a timely manner.

[0067] More specifically, one-way valves 6 and drain ports are matched one-to-one, with multiple valves installed. This arrangement further ensures timely drainage.

[0068] In this embodiment, two one-way valves 6 and two drain ports are provided. The two drain ports are respectively attached to the two side walls 13 of the air duct and located between the two bottom water-blocking ribs 4. The one-way valve 6 is a conventional rubber sewage check valve in the art. Its lower opening size meets the requirements of drainage efficiency and air conditioning intake, and avoids the residual water in the one-way valve 6 freezing in winter, which affects drainage.

[0069] In other embodiments, one, three, or more check valves 6 may be provided.

[0070] This utility model also provides a vehicle, including a vehicle body and the aforementioned external circulation air duct module, wherein the vehicle body is provided with a passenger compartment and the external circulation air duct module is connected to the passenger compartment.

[0071] In the vehicle of this utility model, by setting a guide fluid 2 at the air duct inlet of the air duct housing 1, and setting a guide groove on the guide fluid 2, the guide groove extends along the extension direction of the top edge of the air duct inlet and is provided with an outlet, so that during operation, rainwater and other liquids flowing down the water dam along the ventilation trim panel 100 can be guided and concentrated to flow out, avoiding rainwater and other liquids being directly sucked into the air conditioning box 200 by the air conditioner, thereby improving the safety and reliability of the vehicle.

[0072] Specifically, the vehicle also includes a ventilation panel 100 and an air conditioning unit 200. The air inlet on the ventilation panel 100 is connected to the air conditioning unit 200 via an external circulation duct module, and the air conditioning unit 200 is connected to the passenger compartment. During operation, the external circulation duct module can guide rainwater and other liquids flowing down the dam of the ventilation panel 100, causing them to flow out in a concentrated manner, preventing rainwater and other liquids from being directly sucked into the air conditioning unit 200 by the air conditioner, thus improving the safety and reliability of the external circulation system.

[0073] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
