The specific meaning of the terms in this disclosure will be understood by those of ordinary skill in the art as the case may be.

Referring to fig. 1 to 11, the present disclosure provides a flow path assembly including a flow path opening part 1, a sealing member 2, and a grating member 3.

Wherein the grating elements 3 are arranged at the flow channel opening part 1 and at the second flow channel opening 102 and/or wherein the grating elements 3 are arranged at the sealing element 2 and at the first communication opening 201.

In the above technical scheme, firstly, the runner mouth part 1 can be in sealing connection with the sealing element 2, so that the sealing communication between the first runner 10 in the runner mouth part 1 and the communication runner 20 in the sealing element 2 is realized, and secondly, in order to prevent high-speed fluid or fluid containing large kinetic energy from impacting the joint of the runner mouth part 1 and the sealing element 2, the grid part 3 can be used for effectively buffering the fluid, dispersing the energy of the fluid, reducing the damage of the sealing joint of the runner mouth part 1 and the sealing element 2 and further ensuring the sealing performance between the runner mouth part 1 and the sealing element 2.

In addition, for the fluid flowing into the first flow passage 10 and the communication flow passage 20, water may be used, for example, but the present disclosure is not limited to the specific type of fluid.

Or for the flow channel assembly, two fluid media may flow through the first flow channel 10 and the communication flow channel 20. For example, the two fluid media may include water and air, and the water may enter from the first flow passage 101 of the first flow passage 10, pass through the first flow passage 10 and the communication flow passage 20, and then be discharged from the second communication port 202, and the air may enter from the second communication port 202 of the communication flow passage 20, pass through the communication flow passage 20 and the first flow passage 10, and then be discharged from the first flow passage 10. Wherein, grid spare 3 can be used for buffering water, prevents that water from causing the destruction to the sealed sealing between the pipeline mouth part 1 and the sealing member 2, promotes sealed performance.

In one embodiment, referring to fig. 1 to 5, the seal 2 includes a sealable body 21 and a first seal portion 22, a communication flow passage 20 is formed inside the seal body 21, the first seal portion 22 is provided at the seal body 21 and located at the first communication port 201, the first seal portion 22 is capable of being sealingly connected with the flow passage port member 1 to sealingly communicate the second flow passage port 102 and the first communication port 201, wherein the grill member 3 is provided at the first seal portion 22, and/or the grill member 3 is provided at the flow passage port member 1 and located at the second flow passage port 102.

In this embodiment, by providing the first seal portion 22 on the seal body 21 and positioning it at the first communication port 201, it is ensured that an effective seal can be formed when the seal 2 is in contact with the flow passage port member 1. The first sealing portion 22 may be configured in any suitable sealing structure and in any suitable shape, and the present disclosure is not limited thereto.

The position where the grating element 3 is disposed may be set at the first sealing portion 22, may be set at the second flow passage opening 102, or may be set at the first sealing portion 22 and the second flow passage opening 102, which is not limited in this disclosure.

For reasons of tightness, the seal body 21 and the first seal part 22 can be constructed as a single piece, so that the sealing of the connection surfaces is reduced as much as possible.

For the purpose of detachable or local replacement, the first sealing portion 22 may also be detachably connected to the sealing member body 21, so that the sealing performance between the first sealing portion 22 and the sealing member body 21 should be ensured, and when the first sealing portion 22 is damaged and needs to be replaced, the whole sealing member 2 does not need to be replaced, only the local first sealing portion 22 needs to be replaced, so that the cost is effectively reduced.

Secondly, the presence of this first elastic cuff allows for certain assembly errors to be present, since it is able to adapt its shape during crimping to slight dimensional deviations or irregular surfaces, which can be more tolerant of small errors during manufacturing and installation.

And because the first elastic flanging has the elastic deformation capacity, when external vibration is encountered, the first elastic flanging can play a role in buffering, so that the sealing failure caused by the vibration is prevented, and the stability of the sealing is further improved.

In addition, the first crimping edge 12 is specifically designed to mate with the first resilient cuff, which not only simplifies the installation process (only requires application of appropriate pressure in the first direction a), but also ensures consistency and accuracy of each installation, and reduces errors due to human factors. Furthermore, the grating elements 3 are arranged inside the first crimp edge 12 and connected to the first crimp edge 12, which first crimp edge 12 facilitates the connection of the grating elements 3 and enables an effective protection of the grating elements 3.

The flow passage assembly of claim 9 wherein the open area of the first flow passage at an end distal from the communication flow passage is a first area and the open area of the first flow passage at an end proximal to the communication flow passage is a second area, the first area being 1-2 times the second area.

11. The flow channel assembly of any one of claims 1-7, wherein a length of the first flow channel is greater than a length of the communication flow channel.

12. The flow channel assembly as claimed in any one of claims 1 to 7, further comprising a flow channel member having a second flow channel formed therein,

Wherein one of the flow passage member and the flow passage opening member is movable relative to the other and has a communication position in which the second flow passage can be in sealing communication with the first flow passage through the seal.

13. The flow channel assembly of claim 12, wherein the length of the second flow channel is 1-1.5 times the length of the first flow channel.

14. The flow channel assembly of claim 12, wherein the direction of extension of the first flow channel intersects the direction of extension of the second flow channel.

15. A vehicle comprising a front hatch and the runner assembly of any one of claims 1-14;

16. The vehicle of claim 15, wherein the second flow passage of the flow passage member includes a third flow passage opening;

17. The vehicle of claim 16, wherein the second flow passage extends in a fore-aft direction and the first flow passage extends obliquely upward in a direction away from the second flow passage.

18. The vehicle of claim 17, wherein the first flow passage extends rearward and obliquely upward in a direction away from the second flow passage, and the first flow passage is inclined at an angle of no more than 30 degrees relative to a horizontal plane.

19. The vehicle according to claim 16, wherein the runner section is disposed near an outer side of the vehicle in a left-right direction, and/or the runner section is disposed near an outer side of the vehicle in the left-right direction.

20. The vehicle of claim 19, wherein there are two of said flow path assemblies, one of said flow path assemblies being disposed adjacent an outboard side of a left side of the vehicle and the other of said flow path assemblies being disposed adjacent an outboard side of a right side of the vehicle.
